Remag (SmCo1:5)

Samarium Cobalt Magnets (SmCo1:5)

In comparison with NdFeB magnets, SmCo magnets work at higher operating temperatures and have better temperature stability. Due to their high magnetic properties they are particularly suitable for applications where the relationship between magnetic properties and the size of the magnet is very important.
Interesting for applications which require low magnetization fields at high temperature stability and coercivity.

      Remag (SmCo2:17)

      SmCo magnets have much higher coercivity than AlNiCo magnets, which means that they require more force to demagnetize them. They also work at higher operating temperatures and have better temperature stability than NdFeB magnets.
