Irregular Neodymium Magnet

Now people's daily life, small watches, mobile phones, cameras, phones, tape recorders, computer hard drives, optical drives, large cars, generators, medical equipment, Gauss Meter, aerospace, etc. It is because of extensive use of rare earth permanent magnet materials, the size of many electronic products were able to further reduce the performance greatly improved. To accommodate today's electronics light, thin, small trends. Now, rare earth permanent magnet material production and application, has become the measure of a country's comprehensive national strength and the important symbol of national economic development.

   To have a broad market in China, the bicycle example, the bicycle is a traditional pillar industries, development of electric bicycles since 1998, starting at only 54,000 annually, to the annual output of 5 million in 2004 to an average per bike 0.3 kg NdFeB calculation, needed 1,500 tons of magnets, is equivalent to 2,500 tons of rough
