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.
