Nimonic 80A, also known as Alloy 80A, UNS N07080, and W.Nr. 2.4952 and 2.4631, is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F). It offers high strength and excellent creep resistance at elevated temperatures, making it suitable for high-temperature applications such as gas turbine engineering, aerospace, and industrial furnace components. Nimonic 80A is also known for its good corrosion and oxidation resistance in high-temperature atmospheres.
