About Products

Sintered Rare Earth NdFeB Magnet: is one of the high performance rare earth

permanent magnets, which use neodymium (Nd), iron (Fe), and boron (B) as

their main ingredients.

1. The NdFeB magnet has high remanence, high coercive force, high energy

product and high ratio between performance value and product cost.

2. It can be easily formed into various sizes.

3. Smaller size and lighter weight in designing devices


N35-N52, 33M-50M, 30H-48H, 30SH-45SH, 30UH-40UH, 28EH-38EH, 30AH-


Shapes and sizes:

Disc, Ring, Block, Segment, Cylinder, Trapezoid, Customized Design.

Various kinds or according to customers' request .
