烧结钐钴（Sintened SmCo）

Permanent magnet materials and devices provider

钐钻磁铁具有较高的磁能积极低的温度系数并耐高温，其使用温度可高达500。C。同时具有很强的抗腐蚀性和抗氧化性。因此，钐钴磁钢通常不需要作电镀处理，且被广泛应用在马达仪表传感器、探测器旋动机雷达殛其它高科技领域。

The biggest advantage of SmCo magnet is its high working temperature---500 degree centigrade it doesnt need tobe coated because its difficult to be corroded or oxidized SmCo magnet is widely used in motors. instruments,sensors,positional detectors,generators,radars,etc.
