Sintered NdFeB are formed by powder metallurgical processes. The magnetic performance of all grades is optimized by applying a magnetic field during the pressing operation, thus producing a preferred direction of magnetization (anisotropy). Our sintered NdFeB magnets have 4 distinct characteristics: High corrosion resistance and Low temperature coefficient, Large dimensions or Small sizes. The newly developed Sintered NdFeB Series has outstanding corrosion resistance and high working temperature compared to the normal grades.

segment / tile / arc magnets is one popular shape of Rare earth magnets and perment magnets. It is always manufactured via Cutting, Slicing, Centerless grinding, etc .
segment / tile / arc magnets have the following important factors such as, OR x IR x H x Degree,, etc

Sizes: OR x IR x H x Degree, Customized;

Tolerance: ±0.05mm, Customized;

Coatings: Passivation, Nickel, Zinc, Tin, Aurum, Copper, Epoxy, Chemical, etc.
