Iron chromium Cobalt (FeCrCo) magnets are similar to some low-grade Alnico magnets in magnetic property, but they have better mechanical property. FeCrCo alloys can be easily hot deformed and machined. There are practically no limitations of their shapes and sizes. They can be made to block, square rods, round rods, tube, strips, wire. FeCrCo magnets are beneficial combination of magnets and mechanical properties. Their maximum working temperature can be as high as 400°C.

FeCrCo magnets are widely used in aviation, automobile instrument, compass, oil exploration, hydraulic gauge, computer-embroidering machine, signal generator, counter, hearing aid, medical machine, guard against theft, alarm system, etc.
