samarium magnets (SmCo)

Samarium magnets (SmCo-based magnets) also belong to the group of rare-earth magnets. As compared with  neodymium magnets, they show a lower value of the maximum energy product, approx. 250 kJ/m3, thus their magnetic field is weaker. However, they are corrosion resistant, they can work at temperatures up to 300°C and their magnetic parameters decrease significantly slower with an  increasing temperature than those of neodymium magnets. The Curie temperature is approx. 700°C, these magnets can be thermally demagnetised at temperatures above 800°C.

samarium magnets for extreme conditions

Samarium magnets are mainly used for products where high corrosion resistance, high operating temperature, and low level of temperature effect on the resulting parameters are required, which can be for example in special electric motors, magnetic couplings, and other types of products with high reliability requirements.

we focus on

  • supply of SmCo magnets for heavy-duty industrial applications
  • testing of magnetic properties
  • development of new products with magnets
