Cobalt - Waspaloy Bar (Solution Treated)

Waspaloy is a precipitation hardening, nickel-based alloy which has been used in elevated temperature applications. The alloy has been used for gas turbine engine parts which require considerable strength and corrosion resistance at temperatures up to 1600°F (871°C). Waspaloy is usually vacuum-induction plus consumable electrode remelted.

Corrosion Resistance
Waspaloy has excellent resistance to corrosion by combustion products, encountered in gas turbines and aircraft jet engines, at temperatures up to 1600°F. Intergranular oxidation occurs at temperatures above 1600°F.

Turbine compressor blades and discs, shafts, spacers, fasteners, miscellaneous jet engine hardware.

MasterSource offers a complete line of Waspaloy inventory as noted below.
