Nimonic 75 alloy, an 80/20 nickel-chromium alloy containing controlled titanium and carbon additives, was first introduced in the 1940s for prototype Whittle jet engines. It is now primarily used in thin plate applications requiring oxidation resistance and anti-scaling properties, as well as in high-temperature environments demanding moderate strength. The alloy remains essential in gas turbine engineering and industrial heat treatment processes, including furnace components and thermal processing equipment. Notably, it offers exceptional ease of manufacturing and welding.
The density of the alloy is ρ=8.37g/cm³.
