Features of Fe-Cr-Co Permanent Magnets
FeCrCo magnets, a new type has come into the world in the 1970's. These magnets' properties are featured with higher permanent magnetic property, comparable to those of cast AI-NI-Co magnets, and with a good ductility in the as-quenched state,but with Co content 50% smaller than AlNiCo magnet. FeCrCo machinable permanent magnetic alloy is also famous for its great plasticity, ductility and machinability,this performance far better than casting permanent magnetic alloys, while its high working temperature outshines that of NdFeB permanent magnet. They can be made into semi-hard magnetic alloy, especially suitable for making the small and thin elements with accurate dimensions and complicated shapes, such as wire, tube, bar, strip, etc., with strip as thin as 0.05mm, wire products as thin as 0.1mm, if mechanically processed by filing, milling, digging, drilling and punching.
