Dongyang Aviation Magnetic Ltd is one of the leading China ring shape ndfeb magnet manufacturers and suppliers,Website:http://www.zjmagnet.com, welcome to wholesale or buy neodymium ring magnets from our factory.
Rare earth permanent magnetic material is samarium, neodymium with a mixed rare earth transition metal (such as cobalt, iron, etc.) composition of the alloy, powder metallurgy method-pressure sintering a magnetic material.Samarium Cobalt rare earth permanent magnet points (SmCo) permanent magnet and neodymium (NdFeB) permanent magnets. SmCo magnet which magnetic energy product among 15--30MGOe, a NdFeB magnet magnetic energy product among 27--50MGOe, known as "the permanent King", is the highest permanent magnetic material.Become a rare earth permanent magnet materials electronic communication technology is an important material used in satellites, radar traveling wave tubes, circulators and micro-motors, micro recorders, aviation equipment, electronic watches, seismographs and other electronic equipment on. A rare earth permanent magnet applications penetrate into automobiles, household appliances, electronic instruments, magnetic resonance imaging, medical and audio equipment, micro motor, mobile phones and so on.
