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.
We have the ability to manufacture a full range of neodymium
magnets from N33 to N52, and in various types.
In addition to the shapes we stock, sizes, and grades listed, others are available. Please inquire. irregular shapes and sizes can be machined to your specifications.
