Initially developed in the 1940s for jet engines, superalloys have come a long way since then, emerging as highly versatile materials used across a multitude of industries. Thanks to their unique composition and exceptional properties, such as impressive mechanical strength, surface stability, and resistance to high temperatures and creeping, they are often implemented successfully in a wide range of applications.

In this blog, we will explore superalloys’ role, main features, and valuable benefits in spring manufacturing. We will explain why they are a superior choice for many industrial applications and see how they allow us to tailor our springs to many different needs and projects.

The Properties and Applications of Superalloys

In spring manufacturing, superalloys are extremely valued for their ability to perform exceptionally well under harsh conditions like extreme stress and heat thanks to several critical properties, including:

Excellent mechanical strength.
Surface stability.
Resistance to creeping.

These invaluable qualities make superalloys a preferred material over traditional options like steel and aluminium, especially when it comes to demanding applications such as turbines, jet engines, industrial machinery, and many automotive and aerospace components.

Their robust nature guarantees that the spring designs they are used for will maintain their performance and structural integrity even in the most challenging circumstances. That’s why superalloys come across as an extremely popular choice for experienced spring manufacturers wanting to infuse their products with impeccable, outstanding efficiency and safety.

Industries That Rely on Superalloy Springs

Here are some key industries that benefit from the use of superalloys:

Aerospace and Defence: used in jet engines and spacecraft that rely on high-temperature springs.
Automotive: applied in high-performance engines and exhaust systems to withstand extreme conditions.
Power: critical in turbines and power plants for their durability under high stress and heat.
Chemical: ideal for handling corrosive environments and maintaining structural integrity.
Medical: found in surgical instruments and implants for their biocompatibility and reliability.
Marine engineering: essential for shipbuilding and offshore structures due to their corrosion resistance.
Industrial machinery: employed in heavy-duty equipment and machinery for their long-lasting performance.

Different Types of Superalloys: Strength and Versatility

As we explained, superalloys boast a wide range of properties that make them extremely valuable in spring manufacturing. But what types of superalloys deliver the best results in such a delicate production process? Let’s take a closer look.

Inconel

Inconel is a nickel-chromium-based superalloy particularly known for its oxidation and corrosion resistance, especially at high temperatures; in spring manufacturing, this material excels at providing reliable performance in sectors such as aerospace, automotive, and energy production, as it retains its strength and stability in extreme conditions.

Nimonic 90

Nimonic 90 is another exceptional type of superalloy; its composition includes 50% nickel and 20% chromium, with additions of titanium and aluminium. It is renowned for its high strength and excellent creep resistance at elevated temperatures, making it an optimal choice for improving springs’ longevity and reliability in high-stress, extreme-temperature environments.

Hastelloy

In addition to Inconel and Nimonic 90, Hastelloy is a popular choice for producing springs. This superalloy offers a broad range of options for engineers and designers seeking high durability and resilience; in fact, thanks to its remarkable resistance to corrosion and oxidation, it is particularly suitable for chemical processing industries.

Why Use Superalloys in Spring Manufacturing?

We have briefly touched upon the main reasons why they improve and enhance any spring type; now, it’s time to delve into each advantage in more detail.

Superior Performance in High-Temperature Environments

We have highlighted that one of the primary benefits offered by superalloy springs is their ability to perform at high temperatures. Unlike traditional materials that may degrade or lose strength over time, superalloys are able to maintain their integrity and performance in high-heat environments.

Excellent Corrosion and Oxidation Resistance

We saw that Inconel and Hastelloy, in particular, are extremely resistant to corrosion and oxidation. This characteristic ensures that springs made from these materials have a longer lifespan and require less maintenance, reducing downtime and costs for industries that rely on these components.

Enhanced Safety: Mechanical Strength and Creep Resistance

Mechanical strength, combined with resistance to creep (deformation under stress), makes superalloys ideal for high-stress applications. This is particularly important in industries such as aerospace and automotive, where such qualities are paramount to guarantee safety and overall successful operations.

Adaptability of Superalloys: Custom Springs for Custom Projects

It is evident that superalloys are especially useful in custom projects where standard products and materials fail to deliver the desired results. Whether creating springs for specialised aerospace components or custom parts for complex industrial machinery, superalloys provide the necessary flexibility to design, manufacture, and perfect products that must meet extremely precise specifications and performance criteria.

Custom spring manufacturers leverage such adaptability to deliver unique solutions that address special project demands and create products showcasing superior durability, reliability, and performance. Each project will pose specific challenges, which is why it is incredibly important to assess every request and make sure that each custom spring is designed to perform optimally in its intended application.

You know that springs are our speciality. But how much do you know about springs? While many people can tell what a spring is, identifying it as a helical-shaped component that will compress when exposed to external forces and return to its original form immediately afterwards, they are completely oblivious to the numerous designs and sub-types they come in or how they are made.

As experienced spring manufacturers, we know how vital springs are in various industries across countless systems and specific applications and want to share a little more about them. In today’s blog, we will explore details and interesting facts about one of the most popular spring types we manufacture: compression springs.

Spotlight on: Four Different Compression Styles

When you think about springs, you are likely thinking of compression springs. This type is one of the most frequent and recognisable across a multitude of applications; its main function is to resist highly compressive forces and return to its original shape when the force or load is removed, releasing energy. But we know this, of course. What is interesting, and probably lesser known, about compression springs apart is their availability in a wide range of compression styles, each designed to meet specific requirements. Let’s have a look at each style.

Straight Springs

Straight springs are the most prevalent type of compression spring in various applications. With both the inner and outer diameters remaining constant throughout the length of the spring, their simple design makes them highly versatile and easy to manufacture. We can find straight springs in everyday items such as ballpoint pens, mechanical pencils, and several mechanical devices where reliable performance is essential.

Mini Springs

These spring types are essentially scaled-down versions of straight springs: the two look identical; they are just smaller. Their fantastic compactness and precision make them the preferred choice in the aerospace and marine industries, especially when it comes to delicate instruments and controls, where space is limited but precision is non-negotiable.

Hourglass Springs

As the name suggests, these springs have a distinctive shape. Their diameter tapers at the centre, forming an hourglass shape. This unique design allows for more uniform stress distribution along the length of the spring, providing stability and preventing buckling under compressive loads. Because of this, hourglass springs are often found in complex machinery and automotive components.

Die Springs

Die springs, also known as high-force compression springs, are robust helical compression springs made from rectangular wire and are designed to carry significantly heavier loads than other compression spring types. They can withstand high stress and work fine in difficult and harsh environments, such as industrial machinery, metal pressings, and die-casting applications where heavy-duty performance is essential.

The Five Different Spring Ends

Beyond different compression types, we also have different compression spring ends; each spring end affects the spring’s pitch, height, and overall characteristics, influencing its overall performance and suitability for particular applications. Understanding this aspect will help you choose the right spring, so let’s take a closer look right away.

Open-Ground Springs

Open-ground springs are characterised by their last coil being flat, while pitch is not reduced throughout the rest of the spring. This design provides excellent stability so that the spring stands evenly under compressive forces. For this reason, they are often used in automotive suspensions and industrial machinery.

Open-End Springs

Open-end springs are successfully employed in applications where a steady rate of compression and expansion is critical. They maintain a consistent and reliable coil pitch throughout their length, making them ideal for a wide range of applications, from simple household items like pen mechanisms to complex medical devices.

Closed-End Springs

Closed-end springs feature a reduced pitch at the end of the coil. This reduction in pitch at the ends provides greater stability and support and helps to distribute the load more evenly, reducing the risk of deformation. They are often found in precision instruments and sensitive mechanical assemblies.

Closed-Ground Springs

These springs combine closed-end and open-ground springs. They have a reduced pitch in the last coil and a flat end for enhanced stability and support. The flat end ensures that the spring sits evenly, while the reduced pitch at the ends distributes the load more effectively. They are a popular choice in automotive engines and high-precision industrial equipment.

Specialised Spring Ends

In addition to the common types of spring ends, several specialised designs created to suit specific requirements deserve special mention. For example, double-closed ends, where both ends are tightly coiled, offer even greater stability and load distribution.

Why Spring Safety and Durability Go Hand in Hand

Many people don’t think about spring safety, yet it is absolutely essential for ensuring these components’ longevity and performance. Proper care and regular inspection of compression springs, especially during their manufacturing process, can prevent damage and extend their lifespan. Safety protocols typically involve routine checks for wear and tear and complying with the highest safety standards.

To improve compression springs’ safety, it is important to enhance their durability. spring manufacturers like us employ several valid techniques, for example:

Shot peening is a process that enhances the fatigue strength of the springs by inducing compressive residual stresses.
Plating the springs with corrosion-resistant materials protects them from harsh environmental factors.
Proper installation contributes to the longevity of compression springs.

To commemorate National Apprenticeship Week, we wanted to give some inspiration for those lucky enough to teach STEM subjects such as engineering. Teaching is a fascinating and rewarding career, but despite this, it can be challenging at times, especially when it comes to finding fresh new ideas to inspire the younger generations.

Engaging students in engineering is crucial, as it gives them a better understanding of the science and how it’s beneficial for society. Nurturing and developing students’ interest in engineering should begin in classrooms at an early age. Additionally, it’s vital to make it clear to students that university isn’t the only path and that, as young people, they should keep their options open.

That is why we’re looking into some engineering activities you can use in your classroom to help with lessons and hopefully spark some inspiration in your students to encourage them to continue with their engineering studies and participate in an apprenticeship. We’ll explore various activities that you can do with students of all ages – let’s take a look.

Team Building Activities

Group activities have the advantage of teaching students how to work together and use their strengths for the benefit of the team. It also allows them to develop interpersonal skills and self-confidence. For instance, you could have a paper plane contest. Students can create a design of their own or choose an existing one that they think is the fastest; they can then test this, and the plane that flies the furthest wins. Exercises like these help students develop their critical and spatial skills. It’s also an excellent activity for all ages. Primary school-age children will enjoy the excitement of testing their planes and watching them fly, whereas A-Level or high school-age young adults may see it as more of a competition and want to create the most successful design.

Another group activity that often proves successful is an escape room. This trend started with computer and phone games but has evolved into physical spaces. The idea is to place students in a closed room, and they have to solve clues and puzzles to get out. You can even divide students into teams, and the group that escapes the room with the fastest time is the winner. Not only is this a fun activity, but it allows students to think rationally, make decisions on the spot, grow their analytical skills, and become more confident in expressing their opinions. So get creative and design the escape room yourself in the classroom, or take it as an exciting opportunity to get out and go on a trip.

Experiments

Engineering can be a very practical science, so it only stands to reason that students should experience it that way. Conducting experiments in class will undoubtedly draw the students’ attention, as it’s something more visual and different from anything else they’re used to. In addition, when students see for themselves how engineering can be applied in the real world, they will be more interested in learning its ins and outs.

This is because even though engineering and maths, for instance, are objective and exact sciences, for many, they can be too ‘abstract’. This means that students might find it difficult to see the practicality of what they learn in class. Doing experiments can change that perspective and interest students in engineering. For example, building a functional pinwheel can help students better understand wheel-and-axle mechanisms, and constructing a set of gears will allow them to develop spatial and mathematical skills.

The options are limitless! Teaching engineering in the classroom requires creativity so that you can engage students in this and other STEM sciences from an early age.

Make Your Activities Appropriate for All Learning Types

The above activities are very hands-on and perfect for those who learn best through practical tasks; however, it’s important to remember that not everyone learns best this way and that engineering isn’t always practical. In addition, the industry is so large and needs many different types of people to function as a whole. Consequently, you must include all kinds of learners in your teaching. For example, consider maths-based activities such as data collections as well as visual learning activities such as engaging videos and TV shows.

Try and cover as many learning types as you can in one session – you never know who you’re going to spark some inspiration in.

Ensuring Everyone is Included

Being inclusive is vital and something that we here at European Springs actively encourage. Engineering is a heavily male-dominated field, with women making up just 14.5% of engineers in the UK as of a report made in June 2021.

The key to levelling out these numbers is inspiring younger generations of women, which starts in the classroom. Just one activity completed in a classroom in primary school could spark an interest in a young girl that stays with her all the way through to choosing her career path as an engineer.

Engineering Apprenticeships at European Springs

At European Springs, we’re proud of our work to inspire and encourage younger generations to get involved in the engineering industry.

Springs can be made from lots of different materials, and not all are made from metal. The end-use for the spring will inevitably decide its form and the materials it is made from. Learn the difference between a titanium spring and a copper alloy spring here.

Steel Springs

Steel is one of our favoured materials for creating springs. Steel is iron alloyed with elements like carbon, to create a strong yet pliable spring. Of course, steel isn’t a one-size-fits-all for springs; the purpose of the spring will dictate the percentage of the alloy, as well as how it is treated.

We can produce steel springs for a range of purposes. Here are just a few of the steel types we create springs from:

Cold drawn low-alloy steel
Hardenable spring steel
Stainless spring steel
Stainless spring steel with anti-corrosion
Stainless spring steel for high temperatures
Stainless spring steel, non-magnetic
Combination steel; non-magnetic, anti-corrosion, acid-resistant

Each of these steel types must be carefully chosen, created and modelled into the spring of your choice, and each subtle adjustment to the make-up of the material must change how we approach the spring-making process, too.

We have been spring manufacturers for many decades, however, and are well experienced with the intricacies of spring formation. We also understand that every spring matters, and when it comes to springs for motor industries or healthcare industries, a slack in quality at any point could become dangerous. As such, we pride ourselves on our deep understanding of spring engineering and its value to society. We concentrate on providing springs of a consistent quality for our customers.

Cold drawn low-alloy steels have the benefit of improved tensile strength, and often has a brilliant finished quality that makes it aesthetically pleasing. This could be important if your springs are going to be on show. The low-alloy nature of our cold drawn steels is created by adding in elements such as nickel, chromium, and molybdenum, and depending on the percentages used can grant your average steel spring with greater creep strength.

Our range of stainless steel springs are created from steel with a high percentage of chromium. Regular steel has 10%, but stainless steel uses 17% and some nickel. Stainless steel is best used in applications where yield strength is an important factor, but stainless steel also has high anti-corrosion properties. These properties can be strengthened through subtle tweaks made to the alloy percentages and the finishing of the metal spring.

Stainless steel is almost always cold worked, which can result in magnetism in the spring. This can be an issue in some devices, so it is important to specify or talk to us about whether you will need us to undertake extra work to achieve non-magnetic springs.

More Information About Additional Alloyants

Chromium is a popular alloyant that is used to improve strength, ductility, toughness, and hardness and is present in most types of steel as a result. Other incredibly popular alloyants that are used in carbon steel, which is sometimes referred to as spring steel, includes molybdenum, silicon, nickel, and copper.

We take these for granted, but each of these elements provides their own unique traits. For example, copper is one of the best electrical and heat conductors available on the planet, and silicon is incredibly effective at absorbing shock loads. European Springs also holds the largest stock of silicon chrome wire in the UK, so we’re able to create a wide range of products for a variety of industries and applications.

We understand how the make-up of your springs’ materials will benefit your end project:

Copper Springs

Copper is known for being a fairly soft and ductile metal, which means that it isn’t nearly so suitable as stainless steel is for bearing heavy loads. On the other hand, when the spring also needs to carry an electrical charge, beryllium copper springs might be able to provide the impact strength and anti-corrosion properties that are just right for the product you have in mind.

Primarily used in electrical applications, copper springs can be vital to your final product.

Titanium Springs

In healthcare, the hypoallergenic properties of the metal used might be of the greatest importance. In this case, titanium springs can prove to be the most effective for the end purpose. In contrast to some metals, titanium can be considered a little brittle for everyday use, and it can also be difficult to mould into the desired shape if wielded by an inexperienced company.

When calculated against the pressures it needs to withstand, however, we can figure out how best to solve your problems through the design of our springs.

At European Springs, we test every single type of spring that we manufacture to ensure its strength and durability are up to the mark and can withstand any type of stress and strain.

In any industry, there are great minds and pioneers who lead the way for all those who follow. It’s fair to say that the engineering sector wouldn’t be what it is today without those who made innovations which were well ahead of their time. In this article, we take a look at some of the most important figures in engineering history.

Isambard Kingdom Brunel

Brunel was famous for his innovation; although his projects were not always successful, he achieved many firsts in engineering, and many of his greatest achievements still stand to this day. Although he did not live to see its completion, Brunel is perhaps most famous for the Clifton Suspension Bridge, which had the longest span of any bridge in the world at the time of its construction. Alongside work on bridges, he was also the chief engineer of the Great Western Railway and he built the SS Great Britain, the world’s first ocean going, propeller-driven iron ship.

James Watt

This Scottish inventor and mechanical engineer was pivotal in the Industrial Revolution. Although he did not design the first steam engine (or even the first practical one), his improvements transformed it into a much more powerful machine by adding a separate condenser to make use of energy that was otherwise wasted. By 1790, the steam engine was used in cars, railways, ships and factories on an unprecedented scale, transforming the face of the world.

Ada Lovelace

Flying in the face of engineering and mathematics being perceived as solely masculine activities, Ada Lovelace was instrumental in the development of modern computing. Her notes on the Analytical Engine developed by Charles Babbage include what is thought to be the first algorithm intended to be carried out by a machine, effectively making her the world’s first computer programmer.

Alan Turing

Alan Turing was highly influential in the development of theoretical computer science, where he provided a formalisation of concepts of algorithms and computation with the invention of the Turing machine. This feat of engineering was considered to be a model of a general purpose computer. Due to this invention, Turing is generally considered the father of theoretical computer science and artificial intelligence.

During the Second World War, Turing was part of the Government Code and Cypher School, a codebreaking centre based at Bletchley Park. He devised a number of techniques for breaking German ciphers and played a pivotal role in cracking intercepted coded messages, which enabled the Allies to defeat the Nazis in several battles, the most notable of which was the Battle of the Atlantic.

Thomas Haug

Where would we be without being able to send a text message? In today’s world, it seems almost impossible to function correctly without using your mobile phone to send a message on a daily basis. We have Norwegian engineer Thomas Haug to thank for introducing text messaging in 1992.

Haug led a team of experts from a dozen countries at CEPT (the association of European Telecommunication Operators) in 1982 after he was elected chairman of the committee. In this role, he was in charge of the digitalisation of telecommunications and introduced features such as SIM cards and SMS messaging during his 10-year tenure.

Earlier in his life, Haug was part of the Swedish Board of Telecommunications, where he was engaged in the development of computer-controlled exchanges. He led a project for cellular communication called NMT in 1970; this venture led to the introduction of an analogue system in Saudi Arabia in 1980, followed by four Nordic countries between 1981 and 1982. The NMT enabled automatic roaming between any two users, regardless of national borders and reached 1 million subscribers in 1990.

Elon Musk

Possibly one of the greatest minds of our time, Elon Musk has done plenty for 21^st-century engineering. Musk is the CEO of a number of high-profile businesses, including Tesla, PayPal and SpaceX.

At SpaceX, Musk conceptualised a ‘Mars Oasis’ when founding the company back in 2001, a project that looked to land a miniature experimental greenhouse on Mars containing food crops in a bid to show that human life could be possible on the planet. Since then, the company has made history on a number of occasions, the most notable feat being their ‘Dragon’ spacecraft which became the first commercial spacecraft to deliver cargo to and from the International Space Station.

At Tesla, Musk has successfully brought fully-electric vehicles to the market at affordable prices. Tesla also supply several major car manufacturers, such as Mercedes and Toyota, with affordable electric powertrain systems. In 2014, Musk even announced that Tesla would allow its technology patents to be used by anyone in good faith, as a way of encouraging more automobile manufacturers to develop affordable electric cars.

Of course, these are just some of the most well-known names of history; even today there are many heroes of engineering simply going about their day-to-day jobs. Some will be recognised in their lifetime – the upcoming New Year’s Honours list is likely to recognise a few individuals for their services to engineering – but others may not. We would like to take this opportunity to recognise every engineer for their hard work at developing the world of the future.

As spring manufacturers, we believe that all the innovations mentioned in this article have had a profound effect on the engineering industry and even general everyday life. Here at European Springs, we are keen to continue to build on these fantastic innovations and provide our customers with the very best products and services possible.

Springs can be found in a multitude of technologies we use in our every day lives. Although the vehicles we depend on for our day-to-day transportation needs would not be possible without motor spring technology, the use of springs in the automotive manufacture has changed significantly over the years.

Here, we take a deeper look into the types of springs that have been used in car manufacture throughout the years, and the differences between these.

Leaf Springs

The use of leaf springs in automobiles had been common practice for many years; they were most commonly used in suspension to ensure a smoother ride for vehicles carrying heavier loads. Whilst you will still find this type of spring in some older vehicles (especially in lorries or vans), they have made way for updated materials and components that are more durable and efficient.

The first use of leaf springs in vehicles goes back as far as the early 19^th century, with the first spring-suspension vehicle designed and patented by British inventor Obadiah Elliot. The vehicle consisted of two steel leaf springs on each side of a carriage on both axles to ensure a smoother, more stable ride for carriages carrying heavy loads.

The effect of adding the leaf springs to carriages was so profound that within the next decade most British horse carriages were equipped with them. Although most carriages utilised leaf springs in the form of those invented by Elliot, wooden versions of the springs were also used to cut costs and avoid taxation for carriages carrying lighter loads.

Whilst the use of leaf springs is slowly being phased out by vehicle manufacturers now, these springs have played a vital role in the development of vehicles over the past two century’s. Without the use of leaf springs within automotive design, the smooth ride we experience in our cars today would not have been possible.

In their latest iteration, leaf springs work with the topmost and longest strip of steel, known as the ‘master leaf.’ Being curled at each end to resemble something like an eye, this is then connected to the frame of the suspension. Each leaf spring below the ‘master leaf’ are progressively shorter and less curved to allow the spring to absorb the shock from travelling over a bump or pothole in the road.

Coil Springs

More commonly used in vehicle suspension today, coil springs (also known as helical springs), help to support the weight of the car and allow the vehicle to remain stable, even in extremely rough driving conditions. This type of spring is ideally suited for vehicle suspension, as it can store energy and release it later when needed. It also absorbs shock and maintains force between two contacting surfaces.

When your vehicle goes over a pothole or bump in the road, the coil spring will compress and absorb the impact of the bump. Once the road becomes even again, the spring releases the energy stored and returns to its original state. Due to the shock-absorbing purpose this spring brings, they are built to last and are often coated with a vinyl coating to ensure they are resistant to corrosion.

Coilover Springs

Finally, the most advanced type of spring used in the suspension of vehicles are coilover springs. These springs are only used in the most advanced new vehicles on the market and offer the user of the vehicle the smoothest journey available today.

You’ll find coilover springs at the front and back of a car, offering a consistently smooth ride throughout the vehicle. They also provide exceptionally good performance, which is why you’ll find this type of spring used in all manner of performance and racing cars.

Audi’s Innovative Suspension Springs

With the goal of refining the sphere of lightweight automobiles, Audi released a new type of suspension spring back in 2014.

These springs are unusual in a variety of subtle ways:

The Audi suspension springs were manufactured from glass fibre-reinforced polymer (GRP) in a light green colouration.
The strand of these springs is thicker than the norm and has a larger diameter at the expense of more coils.
The GRP springs are approximately 40% lighter than the springs previously used by Audi, allowing springs of a similar performance to be made according to incredibly lightweight specifications.

The result of utilising these springs has led to more precise driving experience with reduced vibration. The springs also won’t corrode, suffer chemical damage and require less energy to be produced than the more commonly produced suspension springs.

As spring manufacturers, we know the importance of ensuring that all springs we produce are fit for purpose. All of our springs are extremely durable and are made with the care and precision needed to guarantee that we only produce springs of the highest quality.
