A nickel-chromium aged-hardenable superalloy, WASPALOY® offers excellent high temperature strength and oxidation resistance.
With the addition of aluminium and titanium, WASPALOY® has excellent strength at temperatures up to 650°C for critical gas turbine engine applications and good oxidation resistance for non-rotating parts in gas turbine applications up to 870°C.

WASPALOY® is an alloy of choice for both rotating and non-rotating parts in aerospace gas turbines due to its high strength and oxidation resistance at elevated temperatures.
Welding of WASPALOY® is difficult and best performed on material in the solution annealed condition. Limiting the amperage whilst minimising the fusion zone, combined with rapid cooling from welding, is necessary to minimize aging stresses. After welding, the fabrication should be solution treated, using rapid heating and cooling rates through the aging range. This should be followed by a stabilization and aging treatment.
PROPERTIES
Density:8.193 g/cm³
Melting range:1328-1357°C
Waspaloy precipitation hardened nickel based alloys containing cobalt, Waspaloy high-temperature alloys, and Waspaloy have good oxidation and corrosion resistance in gas turbine atmospheres below 760-870 ℃. Waspaloy is used for turbine guide blades, working blades, turbine discs, turbine casings, shafts, high-temperature bolts for flame tubes, structural components, compressor blades, and rocket engine components.
