Choose the Right Material for Your Spring

Spring Material |

From writing pens to wristwatches, springs are everywhere. There’s even that popular toy that is nothing but a big spring. Types of springs are almost as varied as their uses. The same is true of materials that springs are made of. If you’re in the market for springs, choose the material that offers the properties your project demands.


Music Wire

A common material for making springs, music wire is a high-carbon steel wire known for its impressive ability to withstand the stress of compression and decompression without breaking or becoming deformed. It is important to note that music wire is more susceptible to corrosion than other materials.


Stainless Steel

Springs crafted from stainless steel do not have the same strength as those made from music wire, but they do provide better resistance to corrosion. Also, they can withstand higher temperatures – generally up to 500 degrees Fahrenheit – than music wire, which can endure about half that.


Nickel Alloys

Springs made of nickel alloys are able to withstand extreme heat and cold, as well as highly corrosive environments. Because nickel alloys are not magnetic, they are commonly used in devices such as chronoscopes and other indicating instruments.


Copper Alloys

In addition to their superior corrosion resistance and ability to endure subzero temperatures, copper alloys also offer high electrical conductivity. Springs crafted from this more expensive material often are found in electrical components.

Surface Treatment

A host of coatings and other surface treatments are available springs. Some of the most common include:

  • Zinc plating, which helps protect against corrosion.
  • Tin plating, which facilitates easy soldering and improves corrosion resistance.
  • Black oxide, a black coating used mainly for decorative purposes
  • Electro-polishing, a process in which surface material is removed from a spring, giving it a glossy finish, raising the fatigue limit and improving resistance to corrosion.

As you continue to educate yourself about spring materials, be sure to talk to a professional to determine what best suits your needs.

Industries we serve

Natural Gas Industry

The processing and refining of Natural Gas into a marketable products, by separating gas into pipeline-quality natural gas and a stream of mixed natural gas liquids and the transportation of natural gas to through a series of reciprocating compressor stations and pipes, and from there to end users.

Blow Molding Industry

This industry manufactures blow molding machinery. Injection stretch blow molding process has two main different methods, a single-stage and two-stage process; these are the methods by which hollow plastic parts are formed.

Medical Technology Industry

The medical technology industry is an important part of the healthcare sector. It includes most medical devices which aid the prevention, diagnosis and treatment of diseases and illnesses. Established centers of this industry include the United States and Western Europe.
