Waspaloy

Waspaloy is a registered trademark of United Technologies Corp[1] that refers to an age hardening austenitic (face-centred cubic) nickel-based superalloy.

Nickel 58%, chromium 19%, cobalt 13%, molybdenum 4%, titanium 3%, aluminium 1.4%[2] [3] Waspaloy is an age-hardenable, nickel-based superalloy with excellent strength properties through temperatures of roughly 980°C (1800°F).

Other characteristics of Waspaloy include good corrosion resistance, as well as being relatively impervious to oxidation making it well suited for service in extreme environments.

[3] The NIST certified reference material 1243, a standard for X-ray fluorescence spectroscopy, is made from Waspaloy.

Fabrication of this alloy was described as 'very intractable' and was carried out by the engine specialists Bristol, rather than the airframe builders BAC.
