Nimonic Alloy 80A

Nimonic Alloy 80A is a Nickel-Chromium Alloy which has good oxidation and corrosion resistance. Nimonic Alloy 80A also has high creep-rupture and tensile properties at temperatures up to approximately 815˚C. Alloy 80A is made precipitation hardenable by the additions of elements aluminium and titanium.
