Nimonic 80A is a forged and aged-hardened nickel-chromium alloy enhanced with titanium, aluminum, and carbon, specifically developed for use at temperatures up to 815℃ (1500°F). It is produced through high-frequency air melting and casting of extruded blanks. Electroslag refining materials are used for forging blanks. A vacuum refining variant is also available. Nimonic 80A alloy is currently employed in gas turbine components (shims, rings, and discs), bolts, nuclear boiler tube supports, die-cast inserts and cores, as well as automotive exhaust valves.
The density of the alloy is ρ=8.19g/cm³.
