Nimonic Nimonic is a registered trademark of Special Metals Corporation that refers to a family of nickel-based high-temperature low creep superalloys. Nimonic alloys typically consist of more than 50% nickel and 20% chromium with additives such as titanium and aluminium. The main use is in gas turbine components and extremely high performance reciprocating internal combustion engines. The Nimonic family of alloys was first developed in the 1940s by research teams at the Wiggin Works in Hereford, England, in support of the development of the Whittle jet engine.〔("History." ) ''Special Metals.''

Working at Inco's Wiggin facility in the United Kingdom, L.B. Pfeil is credited with the development of Nimonic alloy 80 in 1941. Four years later Nimonic alloy 80A followed, an alloy widely used in engine valves today. Progressively stronger alloys were subsequently developed: Nimonic alloy 90 (1945), Nimonic alloy 100 (1955), and Nimonic alloys 105 (1960) and 115 (1964 - Prof John Gittus FREng. DSc. D Tech 1986.).〔Patel, Shailesh J. ("A Century of Discoveries, Inventors, and New Nickel Alloys." ) ''JOM,'' September 2006. Retrieved: 5 March 2011.〕
