Segment Rare Earth Neodymium Magnets , Permanent NdFeB magnet Nickel Coating
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.

Features
Excellent cost to performance ratio
High resistance to magnetic demagnetization
High flux, High remanence, high coercive force, high energy
Low temperature coefficient and low loss of irreversible
This type magnet is widely used in genetors, motors, 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.
