Nimonic 80A, also known as UNS N07080, is an age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum, and carbon. It has good corrosion and oxidation resistance, high tensile and creep-rupture properties at temperatures up to 815°C (1500°F).
Applications:
Nimonic 80A is used for gas-turbine components (blades, rings, discs), bolts, tube supports in nuclear generators, and exhaust valves in internal combustion engines, and has many other offshore/marine, automotive, and electrical applications.
Normal product forms: sheets, plates, bars, forgings, tubes, strips, and wires.
