Remag Sm2Co17

Samarium Cobalt Magnets Sm2Co17

The combination of high magnetization and high Curie temperature Sm2Co17 magnets is what makes them attractive for many applications that require high energy products and long lasting stability when used at temperatures up to 350 ° C. In addition to Sm and Co, these magnets contain Fe, Cu, and Zr and they present hard magnetic properties when their microstructure is constituated by a network of cells based on 2 / 17R phase surrounded by boundaries based on 1/5 phase. The microstructure is obtained by a metallurgical process including sintering, homogenization and annealing.

Sintered AlNiCo magnets also excel in high maximum operating temperatures and good corrosion resistance. Sintering is better than casting for more complex forms and usually smaller dimensions.

    The main advantages of cast AlNiCo magnets are high maximum operating temperature which can reach more than 500°C and also very good corrosion resistance. Casting is best suited for simple forms and larger dimensions.

      REMAG SmCo5

      Remag SmCo5

      Sintered SmCo5 magnets are produced in a similar way as Sm2Co17 magnets, yet they have lower magnetization and also slightly lower maximum operating temperature. SmCo5 magnets are best for applications where only low magnetization fields can be applied andwhich still require quite high temperature stability.
