Nimonic 80A / Alloy 80A is a precipitation-hardenable nickel-based superalloy that can retain its mechanical strength at elevated temperatures. Its main characteristics are good tensile and fatigue strength at high temperature, strong creep resistance under long-term load, and high resistance to oxidation and scaling. After age-hardening heat treatment, its strength increases significantly; therefore, it maintains better dimensional stability under demanding service conditions where temperature, pressure and continuous mechanical load act together. In short, Nimonic 80A / Alloy 80A is a special nickel alloy used where high-temperature strength, oxidation resistance and long-term mechanical performance are required together.

Nimonic 80A / Alloy 80A is a precipitation-hardenable nickel alloy that is easier to form in the solution annealed condition and gains high strength after ageing. Although it can be machined and welded, tool selection, process sequence and heat treatment control are important due to its high strength. Thanks to its high-temperature creep resistance, fatigue strength and oxidation resistance, it is preferred especially for components operating under mechanical load up to 815 °C.
