Besides hot-pressed magnets and high abundant rare earth permanent magnet, anisotropic bonded magnets are also treated as a choice to fulfil the magnetic performance gap between isotropic bonded NdFeB magnets and sintered Neodymium magnets. Anisotropic NdFeB powder is the base of anisotropic bonded magnets, and anisotropic NdFeB powder can be manufactured by both HDDR technology and crushing hot-pressed magnets.
