The rare earth permanent NdFeB magnetic materials,one of more important areas are supported by  modern electronic information industry  and related people's life,As small as

watches, cameras, tape recorders, CD machine, VCD, computer hard drives, CD-ROM drives, large cars, generators, medical devices,  and more about permanent magnetic materials. It

is due to the widespread use of the rare-earth permanent magnetic materials, many electronic products to further reduce the size, performance has improved significantly.
1.Recent global rare-earth permanent magnet industry
In recent years, Due to high production costs in developed countries, while in the international market, prices are falling , In these countries continuely producing magnets have been unsustainable, and therefore the United States, Europe and the Western developed countries, represented by magnetics enterprises ,they have carried out industrial restructuring,and making NdFeB industry in the international situation has undergone major changes.Sintered magnets, the 2000 U.S. Ugimag company was sold to Magnequench, 2003 Magnequench carried out industrial restructuring of its switched off, it will magnetics shift production to China. The early 21st century, Britain's acquisition of Morgan Group,a subsidiary of Germany's Siemens vacuum smelting company (Vacuumschmelze or VAC) and the United States crucible co, but in June 2003, Morgan Group, shut down the U.S. crucible co (Crucible). 2005 Morgan Group, the German Vacuum smelting company sold the U.S. JPMorgan. Currently, the United States, rare-earth industry, from the glorious past to today's full decline. In Europe only two manufacturers of sintered NdFeB, a vacuum in Germany smelting companies, one in Finland Neorem company. In June 2003, Hitachi Metals purchased Sumitomo Metal Industries Sumitomo under the special payment of the shares to become the world's largest manufacturer of NdFeB, and in April 1, 2004 changed its name to NEOMAX, and stop Hitachi Metals magnet production in the United States . April 1, 2007 NEMOMAX withdraw from the market in Japan, becoming a wholly-owned subsidiary of Hitachi Metals.

There are two Japanese companies, one is a TDK, which is a magnetic material production enterprises established; there is a Shin-Etsu Chemical. NEMOAX, TDK, and Neorem magnets in China, after the processing base has been established. German VAC tricyclic cooperation with the Bureau in 2005, was set up in Beijing in sintered Nd-Fe joint ventures. In addition to the two places in Europe and Japan, the rest of the sintered NdFeB magnet manufacturing enterprises concentrated entirely in China.
Since 1990, the global output of sintered NdFeB magnets was growing rapidly, with an annual growth rate maintained at about 25%. Into the twenty-first century, even though Japan, the United States, Europe and other developed countries the development of rare-earth permanent magnet industry was stalled, but because of China's extraordinary development of rare-earth permanent magnet industry, making the world's rare-earth permanent magnet industry continued to maintain a rapid growth trend. In 2005, global

production was 42.3 thousand tons NdFeB, China's output of 33,000 tons, accounting for 78% of world output, maintaining a strong growth momentum. Japan Sintered NdFeB magnets to mark time in the maintenance of the state. U.S. sintered NdFeB magnets in 2004, all the dead
Bonded magnets, the global production capacity are concentrated in the Japanese companies. Representative of the two companies, one is a Seiko Epson, and their magnetic

production have all been moved to Shanghai EPSON Magnetic Co., Ltd.; another Tatung Co. of Japan. On the computer hard disk drive (HDD) spindle motor applications, Datong and

Shanghai Epson two enterprises accounted for the overall market share of over 90%. By the end of 2002, the shares of the Shanghai Branch tricyclic Epson Magnetic Co., Ltd., in

March 2004 to further expand the options currently held by the Division Ring has 70% of the shares of the company, becoming its largest shareholder. & M in March 2003

acquisition of Taiwan's Hein company, Shenzhen Hein MAG is a bonded magnet high level of technology factories, coupled with the domestic grew up in Chengdu Milky Way, bonded

magnets business except in Japan Datong , the other basically in China.
Bonded NdFeB magnet production in the world's average annual growth rate of 18%, basically maintained a steady growth trend. In 2005, while global production of bonded NdFeB

magnets in 2004 decreased slightly (about 1%), but China's Bonded NdFeB production will maintain a 11% increase. China Bonded NdFeB magnet production has more than 40% of global

production, led the global industry.
2, the status quo of China rare earth permanent magnet industry
To the end of 1983, the domestic rare earth permanent magnet manufacturer less than 10, with the third generation rare earth permanent magnet NdFeB magnet development, a large

number of factories in 1985, emerged after the out. According to preliminary statistics show that China now has a rare earth permanent magnet manufacturer hundred, of which more than 3000 tons annual production capacity there are four, the annual production capacity of 1000 tons -3000 tons of 6, 500 tons of -1000 tons 8. Shanxi because of unique conditions of natural and low-cost, now with the Shanghai-Hangzhou area, the Beijing-Tianjin region of China form a triangular pattern Dingli rare-earth

permanent magnet industry. In 2004, Shanxi had launched production of sintered Nd-Fe-surge of investment in the province within one year of nearly 30 new plants now reached more

than 60 rough plants.
