brief introduction :
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. ndfeb, ndfeb magnet, sintered ndfeb.Super-Strength Rare Earth Magnet.
Sintered NdFeB magnets, have the characteristics of :
*Extreme strong Br Resident induction.
*Excellent demagnetization resistance capability.
*Good Price relative to its high magnetic properties.
*Coating is needed for NdFeB
Surface Treatment Method: Type Information
Metallic Zinc, Nickel, Nickel+Nickel, Copper+Nickel, Nickel+Copper+Nickel,
