NdFeB Magnet

Neodymium Iron Boron Magnet (NdFeB magnet) is mainly formed by Neodymium, iron, and boron. It is the most powerful permanent magnet. Its (BH)max value is 5-12 times of ferrite magnets and 3-10 times of AlNiCo magnets; It’s hcj has 5-10 times of ferrite magnets and 5-15 times of AlNiCo magnets. Its potential magnetism is so high that it can lift up to 640 times its own weight. NdFeB is divided into two kinds of sintered NdFeB andbonded NdFeB. Bonded Ndfeb in all directions are magnetic, corrosion resistant; And sintered Ndfeb because of easy corrosion, the surface needs coating. Generally, the common coating is NiCuNi, Znic, Epoxy. And sintered Ndfeb generally axial magnetization and diameter magnetization, according to the required working face to determine.
