Product name:
Neodymium magnets
NdFeB,the third generation of rare-earth permanent magnet, is the most powerful and advanced permanent magnet today.NdFeB is named as "magnet king" for its high remanence, high coercive force, high energy.Moreover, it has the high performance and high cost ration, because of the rich rare earth resources in China and the ever-changing production process and technological progress .It can be easily formed into various sizes and different shapes, such as segment, ring, block and etc.
Nowadays, it has been widely used in fields such as aviation, electronics, instruments, meters, machine, medical instrument or something like that, it's especially the best choice for various motors, as its thermal stability, along with the improvement of its corrosion resistance and the further development of power electronic device .At present, rare permanent magnet motor has become one of leading trends in the motor development.

About Sintered Neodymium Magnet
Since the foundation of our company in 2005, we have been engaged in the manufacturing and distributing of magnetic materials.At present, we are capable of producing 220 tons of NdFeB per year and our annual sales rises to 6 million dollars.Our products are mainly exported to Europe, America and Southeast Asia.Half of our products are purchased by American or German loudspeaker manufacturers, such as the JBL and AR in the US as well as the Heco in Germany.Thirty percent are sold to electric machine manufacturers like the Italian Cear and the Chinese Baolai.We have earned good reputation in this industry and established long-term cooperative relationship with multiple clients.
Our product features high quality-price ratio.With superior mechanical properties, it is easy to cut and process.The defects of the sintered neodymium magnet lie in the low Curie temperature, poor temperature characteristics, and high susceptibility to pulverization.We have provided solutions to remedy those flaws by adjusting the chemical composition and electroplating the surface.The product we offer can pass the 72-hour salt spray test and its maximum operating temperature reaches 240ºC, thus satisfying the practical application requirements.
Our sintered neodymium magnet has been widely used for the cell phone headsets, high-end loudspeaker boxes, permanent magnet motors, micro motors, gift boxes, handbags, toys, medical instrumentations, instruments and apparatus, metal and plastic products, electronic components, electric car motors, wind turbine generators, and many other items.
Inquires from you are always warmly welcomed.Thanks !
