Product Description
Permanent magnets can be devided into four kinds as below: (1)AlNiCo magnets; (2)the first generation of magnets is SmCo5 which is called 1:5 Samarium Cobalt Alloy; (3)the second generation of magnets is Sm2Co17 which is called 2:17 Samarium Cobalt Alloy; (4)the third generation of magnets is NdFeB which is called Neodymium Iron Boron Alloy. With the development of science and technology, the performance of Nd-Fe-B permanent magnet have been continuously improved and its application fields are expanded. Sintered NdFeB with high magnetic energy products (50 megagauss 400kJ/m3), high coercive force (28EH,32EH) and high temperature coefficient (240C) have been mass produced.

The main raw material of the NdFeB permanent magnets are the rare earth metal neodymium (Nd) 32%, the metal elements iron (Fe) 64% and non-metallic elements boron (B) 1% , adding a small amount of dysprosium (Dy), terbium (Tb), cobalt(Co), Niobium (Nb), gallium (Ga), aluminum (Al), copper (Cu) and the like elements. NdFeB ternary compounds is based on the Nd2Fe14B, its composition should be similar with Nd2Fe14B Formula.
Product Feature
It is have three main parameters: First, Br (Residual Induction), GAUSS of units, which is the residual magnetic flux density when the magnetic field is removed from saturation, representing the external magnetic field strength which it can provide; Second, Hc (Coercive Force), Oersteds of units, Putting the magnet on a reverse magnetic field, its properties will disappear when the applied magnetic field is increased to a certain intensity, the ability to resist the applied magnetic field is known as the coercive force, represents the ability to measure the resistance to demagnetization; Third, BHmax, Gauss-Oersteds of units, which is the magnetic energy from the unit volume of material, it is a physical quantity.
Product Specification / Models
NdFeB, the third generation of rare-earth permanent magnet, is the most powerful and advanced permanent magnet today. NdFeB has the high remanence, high coercive force, high energy.

Because of the rich rare earth resources in China and the ever-changing production process and technological innovation and progress, it has the high performance and high cost ration and it can be easily formed into various sizes and different shapes such as ring,segment, trilateral, block and so on.

In recent years it's thermal stability along with corrosion resistance has been greatly improved. The working temperature of the NdFeB has been able to reach more than 200 degrees, and different coatings can be provided auch as NiCuNi, Double Nickel, Dark Nickel, Bright Nickel, Black Nickel, Chemical Nickel, White Zinc, Blue & White Zinc, Colored Zinc, Black Zinc, Zinc Cr3+, Passivated, Epoxy, Parylene. All our coated magnets are confiming to standards of International Environmental Protection.
Application / Models
It's especially suitable for the all kinds of motors, rare earth permanent magnet motor has become one of the important trends in the motor development.

It widely used in electronics, electric equipment, medical equipment, toys, packaging, hardware machinery, aerospace and other fields, common are permanent magnet motor, speaker, magnetic separation machine, computer disk drives, magnetic resonance imaging equipment, etc.
