NdFeB Ring Permanent Magnets (sintered NdFeB Magnets) of advantage?
1. Chemical composition: Nd2Fe14B.
Neodymium magnets are hard, brittle and easily corrode.
2. Moderate temperature stability
Neodymium magnets lose -0.09 ~ -0.13% of Br/°C. Their working stability is under 80°C for low Hci Neodymium magnets and above 200°C for high Hci Neodymium magnets.
3. Excellent strength value
The highest (BH)max reaches up to 51MGOe .
4. Advanced Technology
The choice of Strip casting and HDDR technology in our factory allows us to make high performance NdFeB over N52 possible.
5. Extremely resistance to demagnetization with Hci
The intrinsic coercive force is over 30,000 Oe.
6. Effective surface treatment to prevent corrosion.
Surface treatments have been developed that allow them to be used in most applications. The treatments include gold, nickel, zinc and tin plating and epoxy resin coating.
 Application:Motors,rotors,windturbines,windgenerators,loudspeakers,magnetic hooks, magnetic holder, filters automobiles and so on.
