Nimonic 80A (UNS N07080)
A nickel-chromium alloy similar to NIMONIC
alloy 75 but made precipitation hardenable by
additions of aluminum and titanium. The alloy
has good corrosion and oxidation resistance
and high tensile and creep-rupture properties
at temperatures to 1500°F (815°C). Used for gasturbine
components (blades, rings, and discs),
bolts, tube supports in nuclear steam generators,
die-casting inserts and cores, and exhaust valves
in internal-combustion engines.
