Incoloy A-286 is a precipitation-hardened high-temperature alloy based on iron, nickel, and chromium, known for its excellent high-temperature strength, oxidation resistance, and corrosion resistance. The alloy exhibits outstanding mechanical properties and creep strength below 650°C, and its heat resistance and structural stability are further enhanced by adding elements such as titanium, aluminum, and molybdenum.
Due to its excellent high-temperature performance, Incoloy A-286 is widely used in aerospace, gas turbines, automotive engines, and petrochemical industries, particularly in the manufacturing of turbine components, fasteners, springs, and high-temperature load-bearing structural parts. Additionally, the alloy also has good machinability and weldability, making it even more suitable for applications in high-temperature, high-pressure environments.
