Product Description

Product Description

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