Samarium-cobalt magnets are primarily composed of metallic cobalt, samarium, copper, iron, and other trace elements. Their advantage lies in their ability to withstand temperatures up to 350°C, coupled with strong corrosion and oxidation resistance. Therefore, samarium-cobalt magnets often do not require electroplating treatment. Samarium-cobalt magnets are widely used in high-tech fields such as sensors, detectors, 5G communication, and radar.
