About Alloy
WASPALOY is a nickel based age hardenable alloy that possesses high temperature strength while still having a good corrosion resistance, especially to oxidation. WASPALOY can be used at temperatures up to 650°C (1200°F) which is critical rotating applications. WASPALOY is used in gas turbine engine components, missile systems, shafts, spacers, seals, rings, casings, fasteners and many other uses in engine hardware, airframe assemblies.
Waspaloy 25 is a nickel- base alloy with excellent high-temperature strength and good resistance to oxidation at a temperature up to 1800° F. This superalloy has higher stability and strength ranges than those available for alloy 718. Waspaloy 25™ can be heat treated through a three-step process: solution treatment, stabilization, and age-hardening.
