Rare Earth ndfeb ring magnet

As you can see in the pictures below, we can produce Neodymium Magnets of various shapes. Commonly seen shapes include Disc, Cylinder, Block, Ring, Countersunk, Segment, Trapezoid, Irregular shapes and more. Needless, we supply magnets of customized shapes. 

Customized

N33, N35, N38, N40, N42, N48, N50, N52 (M, H, SH, EH, UH,AH)
If you are not sure about it, please contact us. We are more than happy to help you. 

Coating is an in alienable component of Neodymium Magnets . It prevents these magnets from oxidation and corrosion. 
Widely used coatings are Ni-Cu-Ni, Nickel, Zn, Gold, Silver, Copper, Epoxy, Chemical, PTFE, Parylene, Everlube, Passivation
