Nimonic 75 is an 80/20 nickel-chromium alloy with controlled additions of titanium and carbon, designed for applications requiring good mechanical properties and oxidation resistance at high temperatures . First introduced in the 1940s for turbine blades in the prototype Whittle jet engines, Nimonic 75 is now most commonly used for sheet metal fabrications that demand oxidation and scaling resistance combined with medium strength at high operating temperatures .
Unlike precipitation-hardenable alloys such as Nimonic 80A or 90, Nimonic 75 is a solid-solution strengthened alloy. Its strength is derived primarily from its nickel-chromium matrix, with minor additions of titanium and carbon providing additional stability . This composition offers excellent fabricability and weldability, making it a versatile choice for gas turbine engines, industrial furnaces, heat treatment equipment, and nuclear engineering applications .
