Xionghai Neodymium Ring Magnets Epoxy plated Rare earth N45,Neodymium Magnet, Sintered NdFeB magnet, the third generation of rare-earth permanent magnet, is the most powerful and advanced commercialized permanent magnet up to date. Neodymium Magnet has high coercive force, high energy and high performance/ cost ratio. It can be formed into various sizes and widely used in many fields such as aviation, electronics, instruments, meters, machines and medical instrument.

Sintering NdFeB magnet Ring

1. Produced by powder metallurgical method with chemical composition of Nd2Fe14B;

2. Excellent cost to performance ratio;

3. Reasonable temperature stability;

4. Very brittle & hard;

5. High resistance to be demagnetized;

6. Poor corrosion resistance to be corrupted;

7. Not suitable for application which is exposed in high temperature conditions.

6. It is always manufactured via Cutting, Slicing, Drilling, and grinding etc.
