Nimonic 75 is an 80/20 nickel-chromium alloy with controlled additions of titanium and carbon. First introduced in the 1940s for turbine blades in the prototype Whittle jet engines, it is now mostly used forsheet applications calling for oxidation and scaling resistance coupled with medium strength at high operating temperatures. It is still used in gas turbine engineering and also for industrial thermal processing,furnace components and heat-treatment equipment.

Nimonic 75 Applications Fileds:
Alloy 75 is most commonly used for sheet metal fabrications which require oxidation and scaling resistanc together with medium strength at high operating temperature. Alloy 75 is also used in gas turbine engines, for components of industria furnaces, for heat treating equipment and fixtures, and in nuclear engineering.
This alloy might be used in any environment that requires resistance to heat and corrosion but where the mechanical properties of the metal must be retained.
