Product Detail

Zhonghao Magnetic Materials Co.,Ltd is one of the leading China block shape ndfeb magnet manufacturers and suppliers welcome to wholesale bar magnets, square strong magnetic from our factory.

Rare earth permanent magnetic materials is the samarium, neodymium mixed rare earth metals and transition metal (such as alloy of cobalt, iron, etc.), by the powder metallurgy method of pressure sintering, the magnetizing field of a magnetic material

Rare earth permanent magnetic materials has become important materials for electronic communication technology, used in satellite and radar TWT, a circulator and micro motor, micro cassette recorder, aviation equipment, electronic watches, seismic instrument and other electronic instrument. Current rare earth permanent magnet application has penetrated into cars, household appliances, electronic meter, magnetic resonance imaging, audio equipment, micro motor, such as mobile phones
