FeCrCo Alloy Magnet – permanent magnetic alloys that are composed of Iron, Chromium and Cobalt. The significant advantage of these alloys is the low-cost shaping possibilities. Anisotropic magnets (with a preferential direction) can be manufactured with heat treatment. In comparison to other permanent magnet materials with similar magnetic properties, FeCrCo Alloys has lower raw material costs.
Typical Applications:
Display instruments
Rotary magnet systems
Hysteresis clutches and brakes
Benefits:
Lowest cost shaping possibilities (e.g. deep drawing and punching)
No chips on edges (in comparison to AlNiCo)
Appropriate cost/benefit ratio
Iron Chromium Cobalt (FeCrCo) magnet has good plasticity, ductility and machine ability, it has the similar magnetic properties with Alnico5. It can be made into semi-hard magnetic alloy, the alloy can be used at higher temperature and has good corrosion resistance. It can be produced to different shapes, such as wire, tube, bar, strip, etc. Sintered NdFeB Single Pole Ring Radial Magnetization Magnet
