Nimonic 80 or Nimonic 80a is a nickel-chromium alloy similar to NIMONIC alloy 75 but made precipitation hardenable by additions of aluminum and titanium. Nimonic 80 has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to 1500¡ãF (815¡ãC). Nimonic 80 is used for gas-turbine components (blades, rings, and discs), bolts, tube supports in nuclear steam generators, die-casting inserts and cores, and exhaust valves in internal-combustion engines.
Available forms of Nimonic 80A are round, hexagon, flats, extruded section, tube, plate, sheet, and wire.
