Samarium-cobalt magnets (SmCo5), comprised of SmCo5 and Sm2Co17, are able to be processed into different shapes according to customer requirements but development limited by the expensive materials. Compared with Neodymium magnets, Samarium-cobalt magnets have a relatively high Curie point and strong corrosion resistance, antioxidant capacity, which makes Samarium-cobalt magnets suitable for high-temperature applications, for instance, motors, instruments, sensors, detectors, engine, radar, aviation, military, communication, medical equipment, instrumentation and electrical devices and sensors and other high-tech industries.
