Neodymium Permanent Magnets are the third generation of rare earth magnets, they are composed ofNeodymium, Iron, Boron and a few transition metals.

The Super strong Neodymium magnets have high remanence, high coercive force, high energy product, andhigh performance /cost.
Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades accordingcustomer's demand.

NdFeB has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.

Nd-Fe-B permanent magnet with its excellent performance, abundant raw material and reasonable price isto be rapid development and wide application.

Also becoming increasingly popular across a wide range of novelty products for markets.

Material: Sintered Neodymium-Iron-Boron.

Size and shape: It will be different according to client's requirement;

Magnetic property: From N35 to N52, 35M to 50M, 35H to 48H, 33SH to 45SH, 30UH to 40UH, 30EH to38EH;we are able to manufacture the full range of Sintered Nd-Fe-B products including the high energymagnets such as N52, 50M, 48H, 45SH, 40UH,38EH,34AH, (BH)max from 33-53MGOe, maximum workingtemperature up to 230 Degrees Centigrade.
Coating: Zn, Nickle, silver, gold, epoxy and so on.

Advantage:high cost-effective, with good mechanical properties, easy cutting; according customer'sdemand to manufacture in a wide range of shapes, sizes and grades.
Shortcoming:the low of the Curie temperature and the temperature characteristics, easy to rust, oxidation,
