All Springs Are Not Equal
Wave Springs offer the unique advantage of space savings when used to replace coil springs. With their smooth, circular coiled sinusoidal wave form, and rolled round edges of pre-tempered wire, Smalley’s edgewound Wave Springs offer many advantages:

  • Reduced spring height by 50%
  • Same force and deflection as coil springs
  • Fit tight radial and axial spaces
  • Over 4,000 standard sizes in carbon and stainless steel.
  • No Tooling Charges for special designs
  • Exotic alloys for all environments

Which Exotic Alloy is right for your application?

We are able to offer several materials that are ideal for sub-sea applications.

What alloy would you recommend for a sub-sea application?

Our AISI 316 stainless steel alloy can withstand the corrosive effects of seawater but, for higher corrosion resistance we can also provide our Smalley products manufactured from Inconel X-750, Inconel 718 and Elgiloy as well as other optional materials.

I am working on a new project that requires all components to be manufactured out of nonmagnetic
material and would like to know what my options are?


For applications requiring truly non-magnetic components we recommend using Beryllium Copper,
Phosphor Bronze or A-286 stainless steel, depending upon the application. However there are other
non-magnetic material available. Typically 302 and 316 stainless steels are thought to be nonmagnetic
but they both become slightly magnetic due to the cold working process used to
manufacture the flat wire. Our Technical Engineers are on hand to discuss your exact application
and to offer their recommendations.

My application requires that the retaining rings are plated for corrosion resistance. What
types of plating options do you offer?


We can offer cadmium, zinc and nickel platings for our Smalley retaining ring products for
corrosion resistance as well as zinc phosphate and black oxide for moderate corrosion resistance. It
is important to consider the type of retaining ring where plating is involved because, if the ring has
multiple turns (or spirals), it can be difficult and expensive to ensure the plating fully covers the
surface between the turns. In these cases we recommend manufacturing the rings in a corrosion
resistant material such as 302 or 316 stainless steel. If higher temperatures are a concern, consider
using 17-7 stainless steel, A-286 stainless steel or Inconel.

For more than 40 years, TFC has been growing to become one of the industry leaders and suppliers
of retaining rings, constant section rings and wave springs. Whether you require a standard or
custom solution, our dedicated team of engineers can design a solution for your target application
performance.
