Well known as Rare Earth magnets, Samarium Cobalt (SmCo) is alloys of the Lanthanide group of elements, which is first kind of commercialized permanent magnet materials from early 1980's. SmCo magnets are available in a number of different grades that span a wide range of properties and application requirements.
SmCo magnets are brittle and machining operations should be performed prior to magnetization, using diamond tools. We are equipped to fabricate these materials to blueprint specifications.
SmCo magnets are anisotropic, and can only be magnetized in the orientation direction. In general, magnetizing fields of about 35 to 45 kOe are required to saturate SmCo materials.
