NdFeB Discmagnet, rare earth disc magnet, neodymium disc magnet

NdFeB magnets are available in sintered as well as bonded forms. The bonded form of the material can be produced with close tolerances off tool, with little or no finishing required. The energy product of the bonded form is much lower than that of the sintered form – up to 10 MGOe. The sintered form usually requires some finishing operations in order to hold close mechanical tolerances.

NdFeB magnets are brittle (though not as brittle as the SmCo types), and machining operations should be performed prior to magnetization, using diamond tools. We are equipped to fabricate these materials to blueprint specifications.

All NdFeB magnets, except the bonded NdFeB B10N material, are anisotropic, and can only be magnetized in the orientation direction. B10N material is isotropic and can be magnetized in any direction, and with multiple poles, although special magnetizing fixtures are required for this. In general, magnetizing fields of about 30 KOe are required to saturate NdFeB magnets.
