SmCo magnets
Sintered Samarium Cobalt Magnets offer the designer a tremendous combination of extremely high magnetic properties, outstanding thermal stability and excellent corrosion resistance. These characteristics 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 or in a corrosive environment.
Two types of SmCo magnets are SmCo5 and Sm2Co17. SmCo5 has a maximum energy product of 18MGOe, compared with 30MGOe for Sm2Co17. The 2-17 composition is also more corrosion resistant and more stable at very high temperature - its maximum working temperature is between 250 °C and approx. 350 °C.
