Alloy family
Nimonic Alloys — Nickel-Chromium-Cobalt Precipitation Hardening Superalloys
Nimonic grades are Ni-Cr based with Co, Ti and Al for γ′ precipitation hardening, offering excellent high-temperature creep strength for turbine blades, fasteners and springs. Main grades: 75, 80A, 90, 95 and 105.
Why specify this alloy family
Creep resistance
γ′ strengthened; retains strength above 750 °C
Applications
Turbine blades, exhaust valves, high-temperature springs
Heat treatment
Solution treatment plus double ageing
