1.Introduction:        

neodymium magnet  is well known as thethird 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 wellas few of other elements like Dy, Tb, Co, Nb, Ga, Al, Cu, etc.

3.Grade:

Standard neodymium magnet  accordingto China National Inindustrial Standard

4.Magnetic force: 

Usually 400-600 times of itself weight within its maxtemperature, the magnetic force can last forever. 

5. Coating or plating: 

Nickel-Cu-Nickel which is environment friendly and can getapproval by third part inspection like SGS. Other coating ways arealso available like Zinc,Gold, Silver, Epoxy, Parylene, etc.  Please kindly refer toTips of coating or visit our company website directly.  Youmay choose coating or not before shipment.  

6. Magnetization: 

usually thickness direction magnetization, if you havespecial purpose and need other magnetization ways, you may remindus when send inquiry to us. Please kindly refer to Tips ofmagnetization or  visit our company website to see moremagnetization ways.  You may choose to magnetize  ornon-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 magneticpole.  Also your logo is possible to printed or carved onthe neodymium magnet .

8.Tolerance:

usually /-0.05mm, if you have more strict requirement, we maycontrol the tolerance within 0.02mm -0.03mm. But the cost will increase accordingly. 

9.Packing :

please kindly refer to our tips of packing. Our packing isstandard for export and has been welcomed by our customers. It canprevent neo magnets from being broken during vibration of shipment,movement, etc.  It also can help the   neodymium magnet from being be affected with damp duringsea shipment
