Special Alloys Nimonic 80

Principal Design Features

A nickel-chromium alloy strengthened by additions of titanium and aluminum. The alloy is used for high temperature, high strength applications.


Gas turbine hot section components.


Conventional machining techniques used for iron based alloys may be used. This alloy does work-harden during machining and has higher strength and “gumminess” not typical of steels. Heavy duty machining equipment and tooling should be used to minimize chatter or work-hardening of the alloy ahead of the cutting.
