Description
Neodymium magnets, 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 *****4MGOe.
Sintered NdFeB magnets are anisotropic and only magnetized in one
direction.
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 Nd2Fe*4B;
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: Ring, others;
9. Ring magnets have the following
important factors such as Outer Diameter, Inner Diameter, Height,
etc Ring
