Waspaloy Alloy

Waspaloy alloy (UNS N07001 / W. Nr. 2.4654) is a nickel-based, age-hardenable superalloy used for wrought and forged components exposed to high temperatures and sustained mechanical stress. It is commonly specified for gas turbines, aerospace, and other high-performance applications where creep strength, oxidation resistance, and structural stability are critical. Ferralloy supplies specialty metals and superalloy forms for demanding industrial applications, along with value-added support, including machining, engineering services, and inventory programs.

Engineers consistently choose Waspaloy for its creep-rupture strength, a crucial factor in demanding applications that require materials to withstand prolonged exposure to mechanical stress at high temperatures.

Waspaloy is widely used in aerospace and gas turbine applications that require high-temperature strength and creep resistance. The material is often selected when a component must retain strength and resist oxidation under sustained exposure to elevated temperatures.

Composition and Key Properties

Waspaloy is a nickel-based, age-hardenable, austenitic superalloy developed for high-temperature strength and oxidation resistance. Key material characteristics include:

• Use in critical rotating applications up to about 1200°F (650°C).
• Use in less demanding applications up to about 1600°F (870°C).
• High-temperature strength in service conditions up to about 1800°F (980°C).
• Hot-forming capability at temperatures of about 1900°F (1040°C) and above.
• Cold formability in the annealed condition.

The ‘face-centered’ cubic superalloy is commonly used in gas turbines and other high-temperature applications, with a density of 8.20 g/cm³ (0.296 lb/in³). The alloy is valued for creep strength, tensile strength, and oxidation resistance in high-temperature service, which is why it is commonly specified for turbine and aerospace components.

Waspaloy material exhibits superior creep and tensile strength, with good corrosion resistance. The alloy’s oxidation resistance is effective under continuous exposure to temperatures up to 1900 ºF (1040 ºC) and during frequent thermal cycling.

Waspaloy material offers high creep and tensile strength along with good resistance to oxidation and corrosion. These properties make it suitable for components exposed to elevated temperature, mechanical loading, and cyclic thermal conditions.

Common Industrial Applications

Because Waspaloy retains strength at elevated temperatures, it is commonly specified for components such as:

• Aircraft engine casings and jet engine components
• Airframe and propulsion system components
• Compressor and rotor discs
• Defense and missile system components
• Furnace hardware used in high-temperature service
• Gas turbine engine components
• Heat shields components
• Propulsion components and systems
• Shafts, rings, seals, and spacers
