Cylinder sintered NdFeB magnet with various coating

The NdFeB material has more advanced properties and multi-polar magnetization, which can make the same size motor generates larger torque or the same powder motor owns more ingenious volume.
So it meets the development demands of the " small, light and thin design" of the motor industry. with these properties, the NdFeB magnets are widely being used in modern advanced industry and high-technology products.
The NdFeb is being widely used in aviation, spaceflight, electron, mechanism, meter and medical treatment field, etc.
