In 1940, England pioneered the development of the NIMONIC alloy. NIMONIC 75, NIMONIC 80A, 81, 86, NIMONIC PE11, and 16 are commercially available NIMONIC alloys.
NIMONIC alloy 80A is a cast, age-hardened alloy reinforced with titanium, aluminium, and carbon. It is made by melting metal at a high frequency and casting it into the air. It has a similar composition to NIMONIC alloy 75. It is resistant to corrosion and oxidation. At 815°C (1500°F), the creep rupture and tensile properties are excellent.
The chemical composition, properties, and applications of NIMONIC alloy 80A are discussed.
