Amorphous alloy strip main manufacturers at home and abroad and production capacity

      The world is engaged in production of amorphous materials only two companies: China antai technology and Japan's Hitachi metals co., LTD. Hitachi metals are bought AlliedSignal companies in the  

       United States in 2003 after a 50% stake and into amorphous alloy business in this field. At the end of 2006, Hitachi has taken the amorphous metal production capacity from the original of about 30000 tons of extended to 60000 tons, which caused Hitachi metals in this field in an absolute monopoly position.   Hitachi metals U.S. factory production capacity of 22000 tons, 30000 tons of new projects in Japan, after the production of the current capacity of about 52000 tons. Hitachi metals of amorphous strip mainly exports to China, the rest of the product supply to India, the United States, and Japan and other countries. Overall, Hitachi metals production capacity of 52000 tons of fully released, supply the       Chinese market of amorphous alloy strip of about 20000 tons to 25000 tons.

      The amorphous, superfine crystal alloy production technology in China develops very fast, strip width under 50 mm strip production technology is mature, there are dozens of domestic manufacturers can produce. But the width in more than 50 mm to 100 mm only 1-2 home can produce. And applied to amorphous alloy transformer core, width 142 mm - 170 mm - 213 mm width of amorphous alloy strip, at home there is no other factory can produce, mainly rely on import from Japan, the United States, so under Japanese price discrimination. However, since 2007, China's research and development, the production of amorphous alloy strip technology leader - Beijing antai technology broadband production technology has been a breakthrough for the company. 142 mm wide strip has developed the trial is successful, the test is still in large-scale industrial production. The development of the company of amorphous industry mainly amorphous microcrystalline alloys by the state engineering technology research center (hereinafter referred to as the national center for amorphous) to provide technical support, this is the national science and technology commission approved in December 1995, establish national center, currently belongs to antai technology company's r&d department, technical ability.

      Antai technology be engaged in the development of amorphous materials have 20 years, due to the long time of amorphous materials than silicon is expensive, and the Chinese government to energy saving technology has no policy support, amorphous material has not been much used in energy saving transformer applications, 1000 tons of antai technology of amorphous strip production line is mainly used in electronics, but since 2005, as the government's emphasis on energy issues and greatly increase in amorphous silicon steel amorphous transformer on price comparison advantage, a sharp rise in demand for amorphous strip, antai technology on the basis of existing production capacity of 3000 tons of amorphous strip on expansion has plans to 40000 tons, to replace imports, to meet the domestic demand. Try each project will be hot in the third quarter of this year, and in the fourth quarter metrics, thirty thousand tons of the construction of the project will be completed at the end of the year. 2008, 2009, 2008, antai amorphous alloy strip production of 3000 tons, 20000 tons and 20000 tons respectively, the 40000 tons of project comprehensive production in 2010. Table 1: the state of global amorphous strip production (unit: tons)
, 2005, 2006, 2007, 2008, 2009, 2010 Hitachi metals, 22000, 22000, 52000, 5500, 8000, 13000, 52000, 60000, 80000 of which export China, antai school of science and technology, 1000, 7000, 30000, 20000, 25000, 25000 domestic other small amorphous materials manufacturers have some, but time is generally shorter, its relatively small investment scale, technical force is weak, only the following products can produce 50 mm, most production at the levels of 100 tons the following strip, and only can produce 50 mm the following in small inductance material of iron core, there is no ability to produce varieties of wide strip is applied to transformer. Lack of domestic leading technology, production scale of the amorphous master alloy, amorphous strip, especially wide strip production enterprises and application of amorphous products production base.
