Neodymium Magnets 
neodymium magnet (also knows as NdFeB, NIB or Neo magnet). Its is the most widely used type of rare-earth magnet. This magnet is a permanent magnet made from an alloy of neodymium, iron and boron. They have replace other types of magnet in the many applications in modern products that require strong permanent magnets.

Peformance of Disc Strong Magnets:
1. High performance, strong coercive force, high energy, etc
2. High resistance to magnetic demagnetization
3. Excellent cost to performance ratio
4. Not suitable for application which exposed to high temperatures.
5. Widely used in mini-motors, wind generators, meters, sensors, speakers, strong magnetic suspension system, magnetic transmission machine and other industrial applications.
6. Very easy to corrosion in humid environments, so it is necessary to do the surface treatment according customers' requirements.
