-- For the time being the focus of global magnetic materials production is in Asia, where Japan specializes in top-end magnetic products, while China and other countries specialize in mid- and low-end products. In recent years the production has been shifting from Japan, Europe and America to China because the country delivers sound "whole set product" to market and offers a sound investment environment. At the end of 2007, the total output value of magnetic materials in China was RMB26.5bn, to which permanent ferrite contributed RMB6.2bn, with the average price of RMB15,000 a ton; soft magnetic ferrite RMB9.3bn, was RMB31,000 a ton; and others including samarium-cobalt magnets, NdFeB magnets and metallic magnets, accounted for RMB11bn of the market.
There are now 1,096 magnetic materials producers in China, of which 359 focus on ferrite, 226 on rare-earth and metallic magnets, with the rest producing associated equipment and auxiliary raw materials. Of the ferrite producers, 197 produce permanent ferrite, with the annual output of 410,000 tons (of which sintered magnets account for 360,000 tons and bonded magnets 50,000 tons); 162 produce soft magnetic ferrite, with the annual output of 300,000 tons (of which manganese-zinc ferrite is 260,000 tons, nickel-zinc ferrite and magnesium-zinc ferrite together 40,000 tons); while NdFeB magnets is 40, 000 tons, and AlNiCo magnets 3,500 tons.
China has in recent years greatly improved the quality and quantity of its ferrite magnets, and basically is able to produce magnets up to the standards of the TDK Company. The performance of sintered ferrite, with roll scale as the raw material, can meet the standard of FB4B, while the performance of magnets made of ferric oxide can meet FB5 and FB6 standards. The performance of soft manganese-zinc ferrite, a high-power material, is generally up to the standards of PC30-PC40. There are also a few producers that are able to deliver products up to standards of PC44 and PC50. The ìi value of most high-magnetic-
permeability materials reaches 8,000 and a few producers are able to produce materials with the ìi value of 12,000-15,000.
