  • Eligiloy
  • MP35

In addition to the coil composition material, you may also need your springs to adhere to other specifications. Heat treating, magnetizing, metallic plating and stress relieving are a few alternatives. Coil thickness is another important attribute and measurements of .005” to .120” are standard.



Customers rely on optimal performance from these products. Whether you need support in designing a certain type of spring or have an engineering department equipped to do so, using a coil manufacturer that has a proven track record can be critical in achieving the best possible results.
