Market advantage of magnesium and magnesium alloy products

With the development of material development and processing technology, the excellent performance of magnesium and magnesium alloy products is increasingly played, so that its application has a breakthrough growth. In addition to aluminum alloy, military, aerospace fields, in transportation (especially the automobile industry), 3C(computer, communication, consumer electronics), steel, anticorrosive, tools, sports equipment and other industries have made great application progress. In the past decade, global magnesium production and sales volume increased by 117%, with an average annual growth rate of 8.17%. In the past five years, it reached 10.46% and reached 700,000 tons in 2006. Among them, the consumption of magnesium alloy products has maintained an average annual growth rate of more than 15% in the past 10 years. As the application field of magnesium coincides with the industrial development focus of China, the application of magnesium in China has grown more rapidly, and the average annual growth rate of consumption in the past five years has reached 25%.

About 60% of magnesium is processed into various parts in the form of magnesium alloy. The research and development of magnesium alloy is the biggest breakthrough of magnesium application. Experts from the industry, materials and investment communities agree that the potential value of magnesium and its alloys in the future is significantly underestimated and there is a lot of room for appreciation. Therefore, the research and development and application of magnesium alloy has become the biggest highlight of domestic and foreign material industry, and also the focus of industrial competition. The research of new magnesium alloy materials and technologies has been regarded as an important strategic choice in the new century by the United States, Japan, Canada, Germany and other countries. In recent years, these countries have formulated and implemented a series of national or industrial comprehensive magnesium alloy development plans.

At present, new magnesium alloys are constantly developed, magnesium alloy die castings have been widely used in many industries, and the magnesium alloy deformation processing technology has made great breakthroughs. Magnesium alloys are not only paid attention to in traditional industries, but also constantly appear in more new industries. The improvement of magnesium alloy processing technology and the development of its industrialization not only open up market space for itself, but also become an important choice for material substitution and industrial upgrading of related industries. Therefore, in the global scope, with the application of magnesium alloy materials as the breakthrough point, the relevant processing and manufacturing industries are facing a new round of adjustment of industrial structure and industrial layout, and new market opportunities have emerged.

At present, vigorously developing magnesium alloy and alloy deep processing technology, and developing the magnesium alloy industry chain and industrial group have become the consensus and common action of the government and all levels of production, learning, research and application. During the period of "tenth five-year, the state Ministry of Science and Technology funded pull application and industrialization of magnesium alloy development projects, after five years of efforts, has been preliminarily established from the front to the industrialization of high technology of magnesium alloys development system, in the domestic set up a batch of magnesium alloy application industrialization demonstration base, promote and develop the application of magnesium products in China, pulling the magnesium alloy production soared, Improved the overall level of the industry. During the 11th Five-Year Plan period, further research projects on national magnesium industrialization will be carried out. At the same time, the National High Technology Development Program (863 Program), the Commission of Science, Technology and Industry for National Defense, the National Development and Reform Commission, and the National Natural Science Foundation of China have all given support to magnesium research projects.

Aluminum alloy die casting technology

Aluminum alloy die casting technology has been widely used in aerospace, light industry, building materials, communications, electronics, automotive and other fields. In western developed countries, most of the cylinder heads and half of the cylinder blocks of gasoline engines are made of aluminum alloy die casting, and the proportion of aluminum alloy cylinder heads and blocks of diesel engines is also increasing. In recent years, this trend is also very obvious in our country. Guangzhou Dongfeng Honda Engine Co., Ltd. takes the lead in the introduction of technology to produce a large number of die casting car aluminum alloy cylinder block. Subsequently, Chongqing Changan Automobile Group, Changan Suzuki Automobile Company, Harbin Dongan Automobile power Company, etc. introduced automatic production lines successively in 2002 to die cast aluminum alloy cylinder block of automobile engine. Shanghai Gantong Automotive Accessories company introduced 3 550 T automatic die casting production line, committed to the development and production of larger aluminum alloy die casting parts. Recently, Changchun FAW Group introduced 2 700 T automatic die casting production line, Yixing Jiangxu Casting Company introduced 3 200 t automatic die casting production line, in September 2004, Guangdong Hongtu Technology(Holdings) Co.,Ltd. Introduced 3 000 t automatic die casting machine production line formally put into operation, creating conditions for the production and development of large aluminum die casting parts. The introduction of technology not only cost the country a large amount of foreign exchange, but also increased the cost of casting, but also caused the domestic related enterprises to lose a large part of the market.

Development prospect of waste copper processing resource reuse

Scrap copper processing is an industry of resource reuse, which is strongly supported by the state. In Wenzhou, Zhejiang province, a recent report on this industry has been made, as follows:

Wenzhou copper processing industry started in the 1980s, and processing enterprises are mainly concentrated in Longwan, which is one of the ten pillar industries in this area. According to statistics, in 2008, the city's copper processing industry produced and processed more than 300,000 tons of copper strip, more than 200,000 tons of copper rod and other copper materials, according to the output value of copper sales, the total sales of more than 20 billion yuan, year-on-year growth of 12%. More than 80% of the raw material of these products is scrap copper, mostly imported. In one year, only large-scale enterprises have digested at least two or three million tons of scrap copper. These wastes are smelted and processed in the furnace to produce higher value-added copper plates, copper strips, copper wires, copper bars... Sell to the whole country and even overseas.

As one of the ten key industries supported by the state this year, the non-ferrous metal, wenzhou copper processing industry has become a cluster of copper processing industry in Zhejiang Province, how to better optimize the industry has attracted the attention of the government. Despite the impact of the financial crisis, the sales prospects of copper processing industry in our city are still quite optimistic, and some enterprises are ready to expand production. Xiang Bingyun, head of Wenzhou Jinyun Copper Materials Co., which had sales of 350 million yuan last year and imported more than 10,000 tons of scrap copper, more than 90 percent of which were imported. The products, mainly copper bars and ribbons, were sold in Ningbo and Taizhou.
