NdFeb has the best performance among the rare-earth permanent magnets. It is the rare earth permanent magnet with the strongest magnetic property at present. It has an extreme high BH max and good Hcj, and greatly machinability. It is the most widely used permanent magnet material in the industrial field and known as the “Magnet King”.
As NdFeB is easily oxidized or corroded, it can be plated or coated according to the requirements of the working environment of the product. The coating could be nickel, nickel-copper-nickel, zinc, tin, chromium, black epoxy, phosphorization, not plating, etc. All coatings meet the requirements of RoHS.
NdFeb is the alloy magnet of Neodymium (Nd), Iron (Fe), Boron (B) and some other microelements, produce through the Powder Metallurgy technology. China owns abundant rare earth resources and supplies the world 70% rare earth magnets.
At present, the performance of our products has reached the first-class level of the world. Our products have been widely used in aerospace, medical, electronic equipment, automotive equipment, motors, generators, nuclear magnetic resonance, magnetic levitation, magnetic separator, electro-acoustic fields, etc.
