Waspaloy Composition

Print Email

Waspaloy is an age hardened austenitic, face-centered cubic nickel-based superalloy. Waspaloy alloy is typically used in high temperature applications, particularly in gas turbines. It demonstrates superior 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 such as gas turbine blades, seals, rings, shafts and turbine disks.
