Ring Countersunk Neodymium magnet

NdFeB Permanent Magnets 

   The third generation of rare earth-permanent magnetic ND2Fe14B is the strongest performance of permanent magnetic in the contemporary era. Its possess a high potential magnetic properties, can be easy to be cutting and drilling, so as processing of complex shape. Now, permanent magnetic ND2Fe14B are widely used in aeronautics and astronautics, electronic, electromechanical, instrument, medical treatment. Besides, it also have a growing market in non-technical field, such as toy, jewelry and so on.
