The alloy is a high strength, nickel base, precipitation hardening alloy which gains its high strength through the precipitation of gamma prime as a result of titanium and aluminum additions and through solid solution strengthening from additions of chromium, cobalt, and molybdenum. Precipitated carbides provide additional strengthening by pinning grain boundaries which reduce grain boundary sliding at elevated temperatures. The alloy is used for critical parts that require high strength at elevated temperatures. It is produced by vacuum induction melting (VIM) followed by vacuum arc remelting (VAR) and/or electroslag remelting (ESR). Applications include turbine and compressor discs, shafts, spacers, turbine cases, fasteners and other miscellaneous hardware.

Super Waspaloy alloy is a higher strength, thermo-mechanically processed grade that has slightly lower carbon content and higher titanium and aluminum contents.
