Waspaloy (For Springs)

This age hardenable nickel base super alloy has very good strength in temperatures up to about 980°C (1800°F). It’s strength is generally comparable to that of Rene 41 and is generally superior to that of Alloy 718 at temperatures exceeding 650 – 705°C (1200 – 1300°F).It can be used for any TSMC spring product such as wave springs, retaining rings and compression springs.
Waspaloy is also known as Alloy 685.
