Ni-Span-C Alloy 902 (For Springs)

Tech Spring Manufacturing Corp. is a high quality Metal Spring Manufacturer in Taiwan, offering Wave Springs, Retaining Rings and Constant Force Spring with good quality and reasonable price.

Ni-Span-C Alloy 902 (For Springs)

A precipitation hardenable Nickel-Iron-Chromium alloy having outstanding controllable thermoelastic coefficient characteristics and excellent oxidation resistance in high temperature atmospheres. The alloy can be processed to have a constant modulus of elasticity at temperatures ranging from -45 to +65°C (-50 to +150°F). It can be used for any TSMC spring product such as wave springs, retaining rings and compression springs.
