1. This is neodymium magnet, it is the third generation rare earth permanent magnet.
It is the most powerful and strongest magnet in World at present.
It mainly have two classification according to the different production process, the sintered neodymium magnet and the bonded neodymium magnet.
2. The picture's product is the sintered neodymium magnet, it also name is sintered NdFeB magnet.
Because it's the mainly chemical composition have neodymiu(Nd), iron(Fe), boron(B) and other rare earth material.
3. The disc magnet is one regular and popular shape of sintered NdFeB magnet.
Ourdisc magnet is mainly used in holding equipment. Some small disc magnets with lower energy are also used in auto speakers.
In the package industry, the bag, the magnetic jewelry, magnetic toy still have very large requirement for the disc magnets
