WASPALOY Nickel Cobalt Alloy with Very High Strength at Elevated Temperatures

WASPALOY is an age hardening austenitic (face-centred cubic) nickel-based superalloy. Waspaloy alloy is typically used in high temperature applications, particularly in gas turbines.

Waspaloy is an age-hardenable, nickel-based superalloy with excellent strength properties through temperatures of roughly 980°C (1800°F). Other characteristics of Waspaloy include good corrosion resistance, as well as being relatively impervious to oxidation making it well suited for service in extreme environments.

Waspaloy has useful strength at temperatures up to 760-870°C (1400-1600°F), and good oxidation resistance in gas turbine engine atmospheres up to 870°C (1600°F). The creep rupture strength of Waspaloy is superior to that of Alloy 718 at temperatures above 620-650°C (1150-1200°F). Short time hot tensile strength is inferior to RA718 at temperatures up to 730°C (1350°F).
