Applications for N42SH Super Strength Neodymium Block Magnets
Neodymium super strength magnets are widely used in motors, wind energy, Audioproducts, elecommunications, meters, magnetic resonance product, magnetic levitation product, VCM,MRI,etc. 

As the corrosion resistance of NdFeB magnets is considered poor.Surface coating or plating is therefore highly recommended for NdFeB magnets. All kinds of surface coating are available,like Nickel,Zn,Ni-Cu-Ni,Gold,Silver,Sn,Chorme.We also applied special surface protection to NdFeB magnets,like ABS coating,Rubber coating,PTFE coating,stainless steel case etc.
