- The grades like N48-N52 could meet your requirement on strong power.
- Standard one such as N35 or N38 is enough for your normal applications.
- If you have requirement on the working temperature, please note it.2.Magnetic direction
Common direction of magnetization showed in picture above:
1) Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametrically.
2) Rectangle shape magnets can be magnetized through Thickness, Length or Width.
3) Arc shape magnets can be magnetized Diametrically, through width or thickness.
Special direction of magnetization can be customized as required.
3.Choose the coating according to your project requirement
4.Choose the right shapes you need
5.Packaging&Shipping1)By Express(DHL, FedEx, TNT, UPS ect): Door to door, Short Delivery time, 3-5 days.
