Permanent Magnets Magnetic material

Different magnetic materials (see related links), because of its performance, the price difference, whether in the application areas or in the development prospects are very different, this paper chose NdFeB permanent magnet, ferrite Magnetic and ferrite soft magnetic materials to be introduced.

    Historically, the World Magnetic Materials Center has experienced changes from Europe (before World War II) to the United States (after World War II) to Japan (after the 1970s). The reason is nothing less than following the transfer of the downstream industry chain and to meet the optimization requirements for manufacturing costs. At present, the industry center is undergoing another transfer, in 2005 China produced a total of 290,000 tons of permanent ferrite, soft magnetic ferrite 160,000 tons, accounting for 46.8% of the world's total output and 55.2%, sintered NdFeB The total output of bonded NdFeB also reached about 34,800 tons, accounting for more than 70% of the world's total output, China has become the world "magnetic are".

And the previous transfer the same, China can become the center of the magnetic materials industry, the most important driving force is still derived from the cost and industry chain two aspects.

In terms of cost advantages, China has a huge cost advantage in terms of manpower, land, water and electricity, and China is one of the world's largest producers of neodymium, iron phosphorus, iron red, manganese tetroxide and strontium carbonate. The main raw material to obtain the obvious advantages.

Due to cost advantages, adequate human and material resources and a broad market space to support the domestic manufacturing industry rapid and stable growth, China deserved to become the world's "manufacturing plant." While the downstream industry of magnetic materials in China's vigorous development, providing a huge market demand for space.

Because there are no other regions in the world that can provide such a superior production environment for the magnetic material industry, the transfer of magnetic materials to China has become a long-term trend.

The next five years the industry development variables increase

Over the past decade, China's magnetic materials industry capacity expansion are very rapid, mainly due to the common development of domestic and foreign enterprises. On the one hand, the production capacity of domestic enterprises in the continuous improvement, which also emerged in the Division III, Ningbo Yunsheng, Hengdian East magnetic, Tiantong shares such as technology and scale advantages of the company. On the other hand, the developed countries of the magnetic materials manufacturing enterprises, due to local production costs are too high, the production capacity and technology transferred to the more backward areas, and both the advantages of cost and industry chain China has become the first choice. According to incomplete statistics, the current enterprises have been in the mainland or co-operation of the well-known enterprises, including Japan's TDK, FDK, EP-SON, Hitachi Metal, Sumitomo, South Korea's pear, three and European PHILIPS, VAC, EPCOS, the United States Of ARNORD, MAGNEQUENCH and so on.
