By Grade
NEODYMIUM IRON BORON MAGNETS – Magnet Grade
Magnet Grade – Known as third generation of Rare Earth magnets, Neodymium Iron Boron (NdFeB) magnets are the most powerful and advanced commercialized permanent magnet today. Since they are made from Neodymium, one of the most plentiful rare earth elements, and inexpensive iron, NdFeB magnets offer the best value in cost and performance.
Sintered NdFeB Magnets By Grade
NdFeB magnets are available in both sintered and bonded forms. Sintered NdFeB offers the highest magnetic properties (28 MGOe to 50 MGOe) while Bonded NdFeB offers lower energy properties. Although bonded magnets do not possess magnetic properties as advanced as those of sintered magnets, they can be made in shapes and sizes that are difficult to achieve with sintering.
A variety of coatings can be applied to the magnets’ surface to overcome the principle drawback of neodymium-based magnets, their tendency to corrode easily.
Neodymium Magnet Grade: N27-N52, 30M-50M, 30H-48H, 30SH-45SH, 28UH-40UH, 28EH-38EH, 28AH~35AH;
