钐钴磁铁SmCo，是一种稀土磁铁，是钐、钴和其他稀土金属材料经配比，熔炼成合金，经粉碎，压制、烧结制成一种磁性材料。

工作温度：250℃，350℃。

它具有具有高磁能积，耐高温，工作温度可达到350℃，温不限，在工作温度180℃以上，其磁能积（BHmax）、矫頑力（coercivity）、温度稳定性和化学稳定性均超过钕铁硼永磁。

钐钴具有强抗腐蚀和抗氧化性，所以被广泛应用于航空航天、国防、微波器件，医疗设备、通讯设施、仪器仪表、电机、传感器、磁力起重器以及磁性传动装置等。

Smco magnet, is a kind of rare earth magnets,samarium, cobalt and other rare earth metal materials by a certain proportion, melting into the alloy, through crushing, pressing, sintering a magnetic material.

Working temperature:250℃，350℃.

High magnetic energy product, high temperature resistant, the highest working temperature can reach 350 ℃, low temperature, unlimited in operating temperature above 180 ℃, the maximum magnetic energy product (BHmax), coercive force (coercivity), temperature stability and chemical stability than ndfeb permanent magnet.

Samarium cobalt has strong corrosion resistance and oxidation resistance, so they are widely used in aerospace, national defense, microwave devices, medical equipment, communication facilities, instruments and meters, motors, sensors, magnetic jack and magnetic transmission device, etc.
