SmCo Magnet

　

Sintered Samarium Cobalt Magnets, available the designer a tremendous combination of extremely high magnetic properties, outstanding thermal stability and excellent corrosion resistance. These Characters make SmCo the ideal material in applications like servo-motors, pump couplings, and sensors, particularly where the magnet is required to operate at high temperature, across a broad temperature range of in a corrosive environment.
Two type SmCo magnets are SmCo5 and Sm2Co17, SmCo5 has the maximum energy products of 18MGOe, comparing with the Sm2Co17 30MGOe, 2-17 composition is also more corrosion resistant and more stable at very high temperature. The maximum working temperature is between 250ºC & 350ºC.
