Special Alloys Nimonic 75

Principal Design Features

A basic nickel-chromium alloy strengthened by the addition of titanium. Used for high temperature oxidation resistant applications.


Gas turbine hot section components and industrial furnace structural parts exposed to high temperature.


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.
