Neodymium Iron Boron
Magnetrons produced from Nd-Fe-B provide the “biggest bang for the buck”.  This is the strongest grade of magnetic material and well is well suited for magnetron design and construction.  It is prone to corrosion, however, when submersed in liquids.  As such, for magnetrons exposed to the cooling media, either a hermetic seal will be required or Sm-Co materials should be utilized.  Additionally, these magnets have a typical  upper thermal limit of about 100°C in assembly (specialty higher thermal limit grades are available up to 200°C).

High performance actuator and motor design requires the use of materials that push the limits of material science.  Magnet material selection is critical and we can assist in the selection of the best material.  Tradeoffs in the selection include temperature, residual induction, coercivity and environment.
