Product features:
 NdFeB magnet, the third generation of rare-earth permanent manget, is the most powerful and advanced permanent magnent today. NdFeB is named as"Magnet King"for its high remanence, high energy. Moreover, it has the high performance and high cost ration, because of the rich rare earth resources in China and the ever-changing production process and technongical progress. It can be easily formed into various sizes and diffierent shapes, such as segment, ring, block,etc.
