1.Introduction permanent neodymium DC motor magnet:    
    
neodymium Ndfeb Magnet For DC Motor Segment Shape magnet is well known as the third generation of rare earth permanent magnet
2.Material Content of Chemical element :
made from 32% of Nd, 64% of Fe, 1% of B (Nd 12 Fe 14 B) as well as few of other elements like Dy, Tb, Co, Nb, Ga, Al, Cu, etc.
3.Grade:
Standard neodymium magnet according to China National Inindustrial Standard
4.Magnetic force:
Usually 400-600 times of itself weight within its max temperature, the magnetic force can last forever.
5. Coating or plating of permanent neodymium DC motor magnet:
Nickel-Cu-Nickel which is environment friendly and can get approval by third part inspection like SGS. Other coating ways are also available like Zinc, Gold, Silver, Epoxy, Parylene, etc. Please kindly refer to Tips of coating or visit our company website directly. You may choose coating or not before shipment.
6. Magnetization of permanent neodymium DC motor magnet:
usually thickness direction magnetization, if you have special purpose and need other magnetization ways, you may remind us when send inquiry to us. Please kindly refer to Tips of magnetization or visit our company website to see more magnetization ways. You may choose to magnetize or non-magnetize before shipment.
7. Mark:
When it is necessary, we may mark with black dot or red dot , even "N" or " S" for you to recognize the magnetic pole. Also your logo is possible to printed or carved on the neodymium magnet.
8.Tolerance:
usually +/-0.05mm, if you have more strict requirement, we may control the tolerance within 0.02mm -0.03mm. But the cost will increase accordingly.
9.Packing of permanent neodymium DC motor magnet:
please kindly refer to our tips of packing. Our packing is standard for export and has been welcomed by our customers. It can prevent neo magnets from being broken during vibration of shipment, movement,etc. It also can help the    neodymium magnet from being be affected with damp during sea shipment
