High Precision NdFeb Neo Permanent Circle Magnets in Rare Earth   

 
Knowledge of sintered NdFeB magnet:

 
NdFeBmagnet 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 and so on.
 

Product Description & Specification:
 
 
 Grades
