Iron Chromium Cobalt is a metal alloy of cobalt and chromium developed more than a half century ago. Cobalt-chromium has a very high specific strength and is commonly used in gas turbines, dental implants, and orthopedic implants. This material is machinable and malleable and was originally designed as a replacement for CuNife. It can also be used as a replacement for AlNiCo because of it high remanence, low Hc, high temperature resistance and low temperature coefficient of Br.
FeCrCo comes in both isotropic and anisotropic form and is much easier to form and magnetize. Unlike alnico FeCrCo is ductile: it can be rolled, stamped and bent prior to the final heat treatment. It can be rolled down to very thin strips and does not require any corrosion coating.
