Short Description:
Nimonic 80A is a wrought, age-hardenable nickel-chromium alloy. Alloy 80A is similar to alloy 75 but made precipitation hardenable by additions of aluminium and titanium. Alloy 80A has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to 815ºC (1500ºF).
Product Description
NIMONIC alloy 80A (UNS N07080/W. Nr. 2.4952 & 2.4631) is produced by high-frequency melting and casting in air for forms to be extruded. Electroslag refined material is used for forms to be forged. Vacuum refined versions are also available.NIMONIC alloy 80A is currently used for gas turbine components (blades, rings and discs), bolts, nuclear boiler tube supports, die casting inserts and cores, and for automobile exhaust valves.
Nimonic 80A Characteristic
Recipitation hardening alloys, high temperature (up to 815 °C) for excellent properties
