Sell Rare Earth Neodymium Arc Permanent DC Motor Magnet

详情

1. Neodymium DC motor magnet is the third generation of rare earth permanent magnet
2. Neodymium magnet is made from *2% of ND, *4% of fe, 1% of b (ND *2 fe *4 b) as well as few of other elements like dy, tb, co, nb, ga, al, cu, etc.

3. Grade:
N*5, n*8, n*0, n*2, n*5, n*0, n*2; N*5m~n*0m, n*5h~n*8h, n*5sh~n*5sh, n*5uh~n*2uh, n*0eh~n*8eh, n*0ah, n*8ah
4. Coating or plating:
Nickel-cu-nickel which is environment friendly and can get approval by third part inspection like SGS. Other coating: Zinc, gold, silver, epoxy, parylene, etc.

5. Magnetization:
Usually thickness direction magnetization, if you need special purpose and need other magnetization ways, please remind us. You may choose to magnetize or non-magnetize before shipment.
6. 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.

7. Tolerance:
Usually +/*0.*5mm, if you have more strict requirement, we may control the tolerance within 0.*2mm *0.*3mm. But the cost will increase accordingly.

8. To quote, we need the following information:

1) General magnetic properties

2) Nominal dimension

3) Direction of orientation

4) State of Orientation(need to be magnetized or not)

5) Quantity

6) Magnet size
