As a machinable magnetic material, magnetic properties of FeCrCo magnets are is equivalent to AlNiCo5’s and various options can be utilized to machining process, include drilling, milling, planing, grinding, and stamping, thus can manufacture micro, light, thin, and complex shaped components. The minimum wire diameter and the thinnest thickness of strip only 0.05mm and 0.1mm, respectively. Usage of Cobalt not only influences the intrinsic coercivity, but also affects machinability of material. The temperature stability and corrosion resistance of FeCrCo magnets is also outstanding. Its Curie temperature and maximum working temperature can reach 680 degrees Celsius and 400 degrees Celsius, respectively. Hydrogen resistance expands the range of FeCrCo magnet in some specific applications.
