Nimonic 80a

NIMONIC alloy 80A is a wrought, age-hardened alloy that is strengthened by additives like titanium, aluminium and carbon. It is manufactured by high-frequency melting and casting in air. It is similar to NIMONIC alloy 75. It has good corrosion and oxidation resistance. The creep rupture and tensile properties are high at 815°C (1500°F).
