Rare Earth N42 N45 N48 N50 N52 Block Permanent Big Neodymium Magnet With Ni-Cu-Ni
Neodymium magnets (Nd-Fe-B) is one of the highest property and strongest permanent magnet by now, are made through powder metallurgy manufacturing techniques.
- Mainly component : neodymium(32%), iron(64%), boron(1%), and a few quantity rare earth material, such as Dy, Tb, Co, Nb, Ga, Al, Cu,etc.
- Advantage: 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. At the same time, because of its high remanence,coercive force and maximum energy product,
- Shortage: Neodymium magnet is easily rust and oxidated, so their surface must be plated Zn, Ni, Silver, Gold or made phosphor and epoxy treatment.
- General Application: strong magnet is widely used in servo motor, flat brushless motor, step motor, IT products, Nuclear Magnetic Resonance, speaker and other products.
