Spring manufacturing is a lengthy and immersive process, but like most processes involving metal, it calls for metals with particular characteristics. Besides, the designing and production of springs need expertise in yield and tensile strength of the alloys. 

Typically, spring manufacturing involves several metals, including titanium. Copper and stainless steel. Continue reading to learn more about the different metals used to make springs:



Types of Springs 


Springs come in different sizes and designs, but the most common ones have a wire coiled into a conical or cylindrical shape. When it comes to extension springs, they feature a looped piece whose coils touch each other. However, when you stretch the spring, the coils diverge.

On the other hand, a compression spring is, of course, wound, but the coils don't come into contact with each other. This way, when force is applied to it, the coils come close to one another. 

When force is applied, the torsion spring is built to wound the coil into a more constricted spiral. Torsion springs are usually integrated into everyday items like hair clips and clipboards. 

The last type of coiled spring is called the watch spring. This is twisted into an even spiral instead of the typical conical or cylindrical shape. At the center is one end of this spring, while the other is at the exterior edge. 

Alternatively, you can find springs fabricated without coils. The leaf spring is an excellent example. It features a shallow-arch-like shape, which is typically used in the automobile industry, precisely the suspension system.

The other common non-coil type of spring is the disc spring. This is a washer-like gadget with the shape of a condensed cone. Lastly, elastic and solid open cylinders can be used as springs. Typically, the non-coil type of springs works perfectly as compression springs. 


Metals Used for Spring Manufacturing 




This is one of the most preferred materials for manufacturing springs. If you didn't know, it is an alloy of iron and other elements, such as carbon. This combination creates a sturdy yet flexible spring. Prevalently, steel is a flexible fit for springs. This means the spring's role will determine how it will be treated, along with the alloy percentage. 

There is a wide variety of steel springs, each designed for a different purpose, and they include the following:

Even though all these springs look like they play the same role, they do not. You have to choose depending on your needs, to avoid any issues. Plus, despite how small, every adjustment contributes to the end product's makeup. 




When you think of copper, you think of somewhat soft and pliable metal, and you're right! These characteristics make it perfect for making spring. And while it might not be as durable as steel, it is equally ductile and ideal for heavy loads. 

Furthermore, beryllium copper is the most suitable spring if you require a spring that conducts electricity. It will offer this particular task's required anti-corrosion specifications and impact strength. Copper springs are mainly utilized for electrical uses and can be essential to your end product. 




Another metal commonly used in the manufacturing of springs is titanium. As you'd probably guess, titanium springs are used in the healthcare industry. This is thanks to its hypoallergenic characteristics, making titanium a most useful metal in this industry. 

Compared to some metals, titanium is rather brittle for daily use, and it can be somewhat frustrating to mold it into a specific shape if handled by an inexperienced manufacturer. 


Music Wire 


Finally, music wire is a popular material used for manufacturing springs. More specifically, the wire used is the ASTM A228. This spring wire can defy temperatures up to 1210C, with a C41-60 Rockwell hardness. 

Music wire is an affordable and durable material, which is why it is preferred for making springs. However, it is not ideal for manufacturing springs that will be utilized in extremely hot or moist surroundings since it is vulnerable to rusting. 

So, do not use it in humid and hot spaces. Finally, music wire is also known as spring steel or panel wire. 

Spring manufacturing has become a big industry thanks to the essential applications of springs and wires. Therefore, it is vital that regardless of the products you're manufacturing, it would be best if you choose a capable manufacturer like us to produce your springs from good-quality materials.
