Inconel X-750 UNS N07750 High Temperature Alloys tooling and aircraft structures
Inconel Alloy X-750 (UNS designation N07750) is a nickel-chromium alloy similar to Inconel 600 but made precipitation hardenable by additions of aluminum and titanium. It has good corrosion resistance and oxidation resistance below 980°C, high strength below 800°C, good relaxation resistance below 540°C, and also has good formability and welding performance. This alloy is mainly used to manufacture relaxation-resistant flat springs and coil springs for aircraft engines that operate below 800°C and require high strength. It can also be used to manufacture parts such as steam turbine blades.
