Neodymium-iron-boron magnet: It is the most commercially available magnet and is known as the magnetic king. It has an extremely high magnetic capacity and its maximum magnetic energy product (BHmax) is 10 times higher than Ferrite.
Its own mechanical processing performance is also quite good.
Operating temperature up to 200℃.
And its texture is hard, performance is stable, have very good cost performance, therefore its application is extremely extensive.
However, because of its strong chemical activity, it must be coated on the surface.
(e.g. Zn,Ni, electrophoresis, passivation, etc.)

With a sintered ndfeb Japan, Germany, the European Union in the patent technologies such as the thawing, our country each big sintering factory of collaborative efforts, sintered ndfeb improve the product grade. As a high-tech applications for its comprehensive performance of the constantly improve, the requirements of the surface treatment of sintered ndfeb also greatly increased, the traditional processing method has been unable to meet the requirements of industrial progress. Electronic science and technology university, sichuan, jiaotong university, red rice and other scientific research institutions, from the microscopic molecular structure, essentially perfect surface treatment principle and industrial application technology development, after four years of hard work and the key technology breakthrough. Nanometer claw (3010)
There is no coating treatment for the composite film, and this technology is an original technological process. The active groups contained in the nano film layer have strong resistance to moisture, oxygen, chlorine ion (Cl), carbon dioxide (CO2), etc. The corrosion resistance and bonding ability of organic resin have been greatly improved. Its excellent surface physical and chemical properties will have a significant impact on the application field.
