Sintered Neodymium rare earth magnets are the strongest magnets in the world up to date, with high flux density and high coercivity, the range of energy product is 33--53MGOe. Sintered NdFeB magnets are anisotropic and can only be magnetized in one direction.

Sintered Neodymium rare earth magnets are widely used in Motors, Separators, lifting, sensors, loudspeakers, MRI, VCM, and other electronics, automation systems.

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.

8. Shapes: irregular
