Sintered NdFeB Magnets
Rare Earth Magnets are including Neodymium(Nd) -Iron(Fe)-Boron(B) types and Samarium(Sm)- Cobalt(Co) classes. The most commonly produced material is neodymium-iron-boron (NdFeB). This group of magnetic materials provides the highest available magnetic energies of any material. NdFeB magnets allow small shapes and sizes with high magnetic fields. Energy product range from 28 MGOe to about 52 MGOe.
