Samarium cobalt permanent magnet is a rare earth permanent magnet made of rare earth elements such as samarium and cobalt. Compared with NdFeb, samarium cobalt permanent magnets are better suited to work at high temperatures. It can maintain good temperature stability and chemical stability above 180°. Samarium cobalt permanent magnets are mainly used in defense, aerospace, microwave equipment, medical equipment, communications, instrumentation, various magnetic transmission equipment, magnetic processors, sensors, voice coil motors, magnetic cranes, etc. Samarium cobalt permanent magnet can withstand high temperature 250~ 350 degrees and Curie temperature 700~ 840 degrees. This is the unique samarium cobalt permanent magnet, high magnetic, high operating temperature. However, if an aesthetically pleasing or corrosion-resistant coating is desired, nickel, zinc, gold, or epoxy or other coating may be used. As for the application of samarium cobalt permanent magnets, they are mainly used in very complex working environments due to their good magnetic stability. Therefore, they are very suitable for manufacturing a variety of high-performance permanent magnet rotors.
