SmCo is a kind of permanent magnet, according to the composition, it can be divided into SmCo5 and Sm2Co17, which belong to the first generation and the second generation of rare earth permanent magnet respectively.
SmCo is characterized by high Br, high Hcj and high (BH)max. At room temperature, its magnetic properties are second only to NdFeB, which can reach up to 35MGOe.
Compared to NdFeB, SmCo exhibits excellent temperature properties, corrosion and oxidation resistance, its max operating temperature is 550°C and requires no surface treatment.
Because of the characteristics of SmCo, it can be widely used in aerospace, military industry, medical, precise instruments, high-end motors, microwave devices, telecommunications and sensors.
