General Description
1. Neodymium Iron Boron (NdFeB), the most powerful y Rare Earth magnet available today, possesses high energranging from 8MGOe to 48MGOe and wonderful coercive force
2. As the third generation of Rare Earth permanent magnet, NdFeB products are quite a bit less expensive, and are mechanically stronger and less brittle than SmCo, also density of NdFeB products is about 13% smaller than SmCo products
3. Because NdFeB magnets are more prone to oxidation than any other magnet alloy, for most applications, coating or plating the magnets is recommended..
Characteristics of NdFeB magnet:
1. Extreme strong Br Resident induction
2. Excellent demagnetization resistance capability
3. Good Price relative to its high magnetic properties
4. Coating is needed for NdFeB
Surface Treatment Method: Type Information
