Remag NdFeB

Neodymium Iron Boron (NdFeB) Magnets

Sintered NdFeB (Neodymium Iron Boron) magnets belong to a group of Rare-Earth magnets and have the highest remanence (remaining magnetization after removing the external magnetic field) and coercivity (high resistance to demagnetization). They are produced via sintering technique and are either pressed isostatically in oil or axially/transversally in a pressing tool. They suffer from relatively low corrosion resistance and therefore usually require long-term or short-term surface corrosion protection according to its use in application. These magnets are produced according to customer specifications and can be found in a variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers.

    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.

      Remag Sm2Co17

      SmCo magnets (including Sm2Co17) have much higher coercivity than AlNiCo magnets. This means that they are more resistant to demagnetizing fields. On the other hand they have still significantly higher maximum operating temperatures than NdFeB magnets.
