Sintered Neodymium(NdFeB)magnets are the most advanced commercialized permanent magnet materials today.

With far better permanent magnetic performance compared with traditional magnets,sintered neodymium magnets are the key functional materials for mordern industry. 

NINGBO RICHENG MAGNETICS CO.,LTD have the ability to manufacture a full range of neodymium magnets from N33 to N52, and in various types.

In addition to the stock shapes, sizes, and grades listed, others are available. Please inquire. Non-standard shapes and sizes can be machined to blueprint specifications.
