Sintered NdFeB(Neodymium-Iron-Boron)
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 26--54MGOe.
Sintered NdFeB magnets are anisotropic and only magnetized in one direction. Widely used in Motor, Separator, lifting, sensor, loudspeaker, MRI, VCM, and other electronics, automation systems.
Feathers of
neodymium segment magnet nickel coating:
1. Produced by powder metallurgical method with chemical composition of Nd Fe B;
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: segment / tile / arc
magnets,;
