FeCrCo permanent magnets（コバルト鉄クロム） are new permanent magnet materials that appeared in the early 1970s. Its magnetic properties are comparable to those of AlNiCo permanent magnets, and it has the advantage of being able to be machined. It is especially suitable for small and thin permanent magnet components with precise dimensional requirements and complex shapes. Can be used in telephones, tachometers, micro motors, micro relays, speakers, etc.
