Metal composite material technology can give full play to the respective advantages of component materials, realize the optimal allocation of each component material resources, save precious metal materials, and achieve performance requirements that cannot be met by a single metal. It can not only replace imports and fill domestic gaps, but also has It has a wide range of applications, has good economic and social benefits, and is easy to obtain support and help in all aspects. For example, the development of stainless steel composite materials has always been a high-tech project actively supported and advocated by the National Development and Reform Commission and the Ministry of Science and Technology.
China will become the center of metal processing industry
Due to the performance functionalization and lower cost of heterometallic composites and a wide range of applications, the development potential of traditional metal materials has been improved. The focus of recent industrialization is: the construction of aluminum-stainless steel, aluminum-steel, titanium-steel, copper-steel strip liquid-solid phase composite process production line, steel-stainless steel composite slab centrifugal casting process production line, surface composite finishing technology preparation thin Cladding (0.008MM-0.1MM) metal clad strip production line; development of large-scale production technology of particle-increasing aluminum matrix composite materials, semi-solid forming technology, continuous coating of composite high-speed steel materials and products, and industrialization.
China's manufacturing industry has risen rapidly. As one of the basic industries of the manufacturing industry, the metal processing and forming industry has developed more obviously: in the past few years, the entire industry has developed at an average annual growth rate of 20-30%, and the quality of products is also increasing. The astonishing speed increase has gradually gained the recognition of the whole world manufacturing industry. Taking 2005 as an example, the entire metal processing and forming industry consumes more than 86 million tons of various steel materials, of which more than 20 million tons are imported; tooling and moulds are about 39.5 billion yuan, of which imports account for about 5.8 billion yuan; newly purchased equipment is about 234 million tons. 100 million yuan, of which about 13.4 billion yuan is imported; there are about 40,000 to 50,000 stamping and sheet metal production enterprises, with nearly 1 million employees.
According to data from the National Bureau of Statistics and other departments, the entire metal processing and forming industry, including equipment, molds, raw materials and forming parts, will maintain an annual growth rate of 10-20%. With the further development of China, the strong market demand drives the high growth in the production of sheet metal, pipes, profiles and wires. In the future, 60% of the world's total steel production and consumption will come from Asia, especially China. At present, China's steel production accounts for about 34% of the world's steel production, and its market consumption accounts for about 33% of the world's. It has become the country with the largest steel production and consumption in the world. It is estimated that by 2010, eight major industries including construction, machinery, automobiles, shipbuilding, railways, petroleum, home appliances, and containers will use 261 million tons of steel in 2010. The total market volume of China's metal processing and forming industry is huge, and it is becoming the center of the metal processing and forming industry in Asia and even the world.
1. The growth rate of rare metal composite materials is still relatively fast
With the strengthening of the implementation of the national environmental protection industry policy, the application of rare metal composite materials in power flue gas desulfurization equipment continues to grow. At the same time, the degree of localization of investment in the chemical industry has been greatly accelerated, which also provides a good development opportunity for the development of rare metal materials. In the first half of 2007, the proportion of sales in the chemical industry has exceeded 50%, which is the main growth point. The support of national industrial policies, high technical barriers, and the demand for industrial upgrading have provided a broad space for the development of the industry.
The rare metal composite material industry, as a new type of material, is an industrial structure encouraged by the state. Its traditional application field is the flue gas desulfurization device of the power plant. The further promotion of the national energy saving, pollution discharge and environmental protection policy provides policies for the development of the rare metal material industry. The support from the above also provides a stable foundation for the pulling of industry demand. With the improvement of the national macro economy, the fixed asset investment in the chemical industry is also developing rapidly, and the localization of chemical equipment provides new development opportunities for the development of the rare metal material industry.
After 2005, the application in the chemical industry has developed the most rapidly, and since 2007, it has surpassed the traditional application in the power industry. The structural upgrade of China's equipment manufacturing industry, especially the upgrading of CNC machine tools and large-scale complete sets of equipment, also provides a broad development space for the development of the rare metal material industry. The technical threshold of the rare metal material industry is relatively high. In particular, explosive composite welding requires on-site explosion, while civil explosion requires a license.
Rare metal materials are mainly used in large-scale and continuous chemical and power industries. The accumulation of customers' resources constitutes a high barrier for new entrants who lack technical and scale support. The overall scale of the rare metal material industry is relatively small, and customers' The characteristics of individual demand are obvious, which is not attractive enough for large enterprises with strong financial strength. Therefore, this market constitutes a market obstacle for large enterprises. Other businesses of the company, such as metal fibers, are mainly used for chemical industry, automobile exhaust filtration, and national The promotion of energy-saving and pollution-discharging policies also provides a good opportunity for the development of the industry. Insoluble metal products are mainly used in high-tech industries such as metallurgy, aerospace, nuclear energy, electronics, etc. The rapid development of these industries is also a good opportunity for the insoluble metal products industry.
