NdFeB Magnets Products

Total 8 Product(s)

HPMG are very aware of the growing importance of Rare Earth Magnets generally and NdFeB in particular and have been developing their range with the assistance of the National Institute of Materials(NIM) in China since our production first commenced in 1994.

Our collaboration with(NIM), our own parallel investment initiatives in plant equipment and of course “Research & Development” allows us to present to you a range of products perfectly adapted to your needs, motors, pumps, automotive & industrial applications with excellent performance in terms of reversible temperature co-efficients, corrosion resistance and weight loss.

Involving the sintering of power compacts under vacuum

1、Ginding and slicing possible

2、Very reactive with moisture and oxygen

3、Coasting may be applied depending on the expected enviroment

Application : applied to various electronic motors,engineering equipment,medical equipment ,audio apparatus, and household appliances.
