NDFEB MAGNET
NdFeB magnet
Neodymium magnet (also known as NdFeB, NIB or Neo magnet) has high remanence, high coercivity and high energy product. It is called Magnet King.
NdFeB maagnets has good mechanical properties, easy to process into ring, round, square, arc and a variety of special-shaped products. It is widely used in new energy vehicles, wind power generation, industrial motors, consumer electronics, medical devices and other fields.
Now we are able to make NdFeB magnets grade from N35-N56, N35M-56M, N35H-N54H, N33SH-N52SH, N33UH-N50UH, N33EH-N48EH, N30AH-N45AH.
We make different shape of NdFeB magent
