The bonded NdFeb Magnets material can be made into complicated shapes and packing, as well produced with close tolerances off tool, with little or no finishing required. It is isotropic and can be magnetized in any directon, and with multipe poles. The energy product of the bonded form is much lower than that of the sintered form- up to 10 MGOe.
