Brief Introduction:
Neodymium Magnet is the third generation of rare-earth permanent magnets and the most powerful and advanced commercialized permanent magnet today. NdFeB has high coercive force, high energy and high performance.
Neodymium permanent magnets (ND-Fe-B) are composed of neodymium, iron, boron and a few transition metals.
Performance range of products:
1.Br: From 11.400 Gauss to 14.700 Gauss
2.Hcj: From 11.000Oe to 30.000Oe
3.BH (max): From 30GOe to 52MGOe
