Inconel is a family of nickel-chromium superalloys, with iron as a third major constituent, engineered to hold their strength and resist oxidation and corrosion at extreme temperatures and pressures. Metallurgists at the International Nickel Company discovered it in the early 1930s, with the trademark registered before December 1932, and it saw early significant use in the 1940s when Henry Wiggin and Co, a Mond Nickel subsidiary in England, supplied it for Frank Whittle's pioneering jet engine work. It forms a thick, stable passivating oxide layer that shields the surface from further attack, which has made it standard for turbine blades, rocket engines, nuclear reactors and other parts that must hold their strength under sustained heat.
