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.

Nimonic 80A (For Springs)

Nimonic 80A is a Nickel-Chromium alloy which is precipitation hardenable. It has largely been superseded by Nimonic 90 and Inconel X-750, but because of the low Cobalt content, it is still specified for nuclear applications. It can be used for any TSMC spring product such as wave springs, retaining rings and compression springs.
Nimonic 80A is also known as Nicrofer 7520 Ti, Pyromet 80A, Superimphy 80A, and Udimet 80A.
