SmCo magnet

cylindricalrectangular

Samarium cobalt magnet is mainly formed by the metal samarium, cobalt, and some other rare earth elements of the permanent magnet. SmCo Magnet is only the permanent magnet with high BH max, high Hcj, and high Br. Meanwhile, it has a very low-temperature coefficient (-0.03%/°C) and can be used at both high and low temperatures. The maximum operating temperature is 350°C, and the negative temperature is about minus 200°C. At the same time, it has strong corrosion resistance and oxidation resistance. Therefore, SmCo magnetic steel usually does not need to be electroplated and is widely used in motors, meters, sensors, engines, radar, and other high-tech fields.
