Hangzhou Permanent Magnet Group.,Ltd

NdFeB

Neodymium iron boron (NdFeB) magnets are currently the strongest permanent magnet material with excellent magnetic properties and are widely used in various types of permanent magnet motors, engineering machinery, electro - acoustics, electrical appliances, medical devices, etc. However, NdFeB has a low Curie temperature, poor temperature stability and is prone to corrosion, so surface treatment is usually required.

Hangzhou Permanent Magnet Group (HPMG) has a full set of sintered NdFeB magnet production processes and can produce high - performance products of grades such as N58, 56M, 56H, 56SH, 54UH, 50EH, etc. We also offer high - tech products like grain boundary diffusion (GBD), low/free heavy rare earth, and cerium - containing magnets, which are customized to meet our customers' needs.

Detailed product parameters can be downloaded from the end of this page or from the download section.

HPMG has a complete NdFeB surface treatment process and can customize different high-end polymer and metal coatings on demand.
