Stellite is a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Information is available from the manufacturer, Kennametal Stellite, outlining the composition of a number of Stellite alloys and their intended applications. The alloy currently most suited for cutting tools, for example, is Stellite 100, because this alloy is quite hard, maintains a good cutting edge even at high temperature, and resists hardening and annealing. Other alloys are formulated to maximize combinations of wear resistance, corrosion resistance, or ability to withstand extreme temperatures.
