Description
Iron-chromium-cobalt (FeCrCo) magnets have good plasticity, ductility and machinability, their magnetic properties are similar to those of Alnico5. FeCrCo magnets can be made into semi-hard magnetic alloys, which can be used at high temperatures and have good corrosion resistance. They also can be produced to different shapes, such as wire, pipe, bar, strip and so on.
