Hangseng Magnetech Inc. (SUPERMAG, neoi) is your best source for the highest quality magnets, neodymium magnets, magnetic devices and expert application assistance for OEM, point-of-purchase, industrial and retail markets.
NdFeB magnet is a kind of strong permanent magnet. Its lifetime can be 30 years when the working temperature is reasonable.
The most special feature is that its volume is small, but the pull force is very strong.
It can be used almost everwhere in our life, such as industrial , moto, speaker, arts and so on.

Neodymium Iron Boron (Nd-Fe-B) or Neodymium magnet
ndfeb magnet are extremely strong for their size. Shapes include rings, blocks, discs and custom. To prevent unwanted oxidation, neodymium magnets are usually finished with zinc, nickel or epoxy coating.
NdFeB magnets can be manufactured by sintering, compression bonding, injection molding, and extrusion. The sintered form holds the highest energy product of up to 48MGOe, while the bonded form holds a lower energy product of up to 10MGOe. The majorities of NdFeB magnets are anisotropic and can only be magnetized in the orientation direction. In general, magnetizing fields of approximately 30KOe are required to saturate NdFeB magnets.
