Neodymium Magnets, also known as NdFeB, NIB, or Neo magnets, are the most widely-used type of rare earth magnets. Neodymium Magnets are made from an alloy containing, amongst others, the elements Neodymium, Iron and Boron (NdFeB). It is the strongest type of magnet and manufactured in a wide range of shapes, sizes and grades and different coatings/finishes.
1.Grade cover N35-N52, N30M-N50M, N30H-N48H, N30SH-N45SH, N28UH-N40UH, N28EH-N38EH.
2.Size and Shape:D3--D280mm(round)Cylindrical, Ring, Square, Holed Square, Watt, Arch, or Customized.
3.Coating: Nickel, Nickel copper nickel, Zinc, Golden, Black epoxy, Grey epoxy, Phosphating and so on.
4.Direction of magnetisation:Through the thickness or through the diameter.
a. Magnetization thickness B. Axial magnetization C. Symmetric magnetization D. Multipole magnetization E. Radial magnetization. Special requirements for custom magnetization
5.Application of NdFeB magnet: Toys, Package, Printer, Switchboard, Phone, Vcoil motors (VCM's) in hard disk drives, High performance(maglev, linear and rotary) motors, Bearings, Eddy-current brakes, Brushless DC motors, Magnetic separation, Magnetic resonance imaging, Sensors, Loudspeakers, Jewelry industry and etc.
6.Advantage
1) Excellent temperature stability
2) Small size and light weight
3)Strong magnetism
4)Relatively high energies characterize
5) High performance-to-price ratio,widely used

Magnetic material is not standard product,so you can provide details information to us to make it.

- The grades like N48-N52 could meet your requirement on strong power
- Standard one like N35 or N38 is okay for your normal applications
- If you have requirement on the working temperature, please note it.

5.Packaging&Shipping
1)By Sea: As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton. (Detailed package quantity should be made upon the real products)
2) By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.
