FeCrCo Magnet

What is Iron Chrome Cobalt Magnet ( FeCrCo magnet)?

FeCrCo Magnet is composed of Iron, Chromium, and Cobalt. Raw Materials are vacuum melt to alloy ingot, then alloy ingots can be machined by hot rolling, cold rolling and all machining methods of drilling, turning, boring etc to shape the FeCrCo Magnets.
FeCrCo Magnets have something similar with Alnico Magnet on production and characteristic. FeCrCo Magnets also have high remanence but low Hc which is similar with Alnico 5 Magnets, They also have high working temperature and very low-temperature coefficient of Br which is also similar with Alnico Magnets. They are also made magnetism by a process of heat treatment, and they also classified to the isotropic and anisotropic material by the process of magnetic orientation.
The very difference of FeCrCo Magnets is they are very machinable. As all know, whether Alnico Magnets or Rare earth magnetic materials, they are all brittle, they are only able to be machined by limited methods, For example, grinding and linear cutting. But FeCrCo Magnets can be machined by lots of methods prior to the heat treatment.
Characteristic of FeCrCo Magnets
