Sintered Samarium Cobalt Magnet (SmCo) is characterized by high magnetic properties, outstanding thermal stability and excellent corrosion resistance ability.
The above characteristics make SmCo the ideal material in applications like servo-motors, pump couplings, and sensors, particularly where the magnet is required to work at high temperature in a corrosive environment
SmCo magnets are divided into two types: SmCo5 and Sm2Co17. SmCo5 has a maximum energy (BHmax) of 22MGOe. . Compared with 30MGOe(BHmax) of Sm2Co17, the composition of 2:17 magnets offers better anti-corrosion ability and is more stable at very high temperatures. The temperature environment is 250 0 ~350 0.
