NdFeB Magnets

1、NdFeB Magnets

①The Traits And Applications Of NdFeB

Trait: Br And (BH)Max High, Price Moderate. Corrosion Resistance Is Poor, Generally Need To Coating, Curie Temperature Low, And The Temperature Coefficient Is Big.

Application: Mainly Used In Motor, Poly Filter, Generators, Measuring Instrument, Maglev, Magnetic Drive, Magnetic Resonance, Etc.
