Cheap Manufacturer Hot Sales Strong Sintered used scrap magnets for sales 

 

Summarize: 

   Sintered neodymium-iron-boron(NdFeB) permanent-magnet material was developed in 1983. The major composition of NdFeB magnets is Nd2Fe14B. It is the highest magnetism performance permanent-magnet material at present, that can be made into the complex shape magnet, and cut.

Property: 

      The (BH) max value of the sintered NdFeB magnet is 5 to 15 times higher than sintered ferrite magnets. Hcj value is 5 to 10 times higher than sintered ferrite and 6 to 10 times higher than AINiCo magnets.

      The potential magnetic properties of NdFeB magnets are very high. Theoretically, their (BH) max value can be reached to 527 kJ/m³(66MGOe). They can even attract object which weight is 640 times heavier than themselves.
