Various Ring Neodymium Rare Earth Magnets Used For Speakers , Sensors
Neodymium magnet (Nd-Fe-B) is one of the highest property and strongest permanent magnet by now, are made through powder metallurgy manufacturing techniques. They are mainly composed of neodymium(32%), iron(64%), boron(1%), and a few quantity rare earth material, such as Dy, Tb, Co, Nb, Ga, Al, Cu,etc. Neodymium magnet is regarded as “Magnet King” due to its recorded high remanence, coercive force and maximum energy product. With Neodymium magnet rapid development, many high-tech products were developed. Especially its application in motors makes products miniaturization and micromation. This type magnet is widely used in IT products, Nuclear Magnetic Resonance, speaker and other products. Neodymium magnet is easily rust and oxidated, so their surface must be plated Zn, Ni, Silver, Gold or made phosphor and epoxy treatment.
