"The non-ferrous metal processing industry represented by copper and aluminum in China should accelerate the research and development of new products and new applications, as well as the precise positioning of existing products and the development of new markets on the basis of strengthening technological progress and industrial upgrading. To further promote the sustainable development of the non-ferrous metal processing industry." On September 21, 2012 National Non-Ferrous Metals, sponsored by China Nonferrous Metals Processing Industry Association, Guizhou Provincial Development and Reform Commission, Guiyang Municipal People's Government, and China Aluminum Corporation Industry experts at the Technology Progress Industry Upgrade Conference and the Guizhou Nonferrous Metals Processing Industry Development Seminar, industry experts said. The difficulty of stable industrial development is still in the rapid development of China's copper and aluminum processing industry during the five-year plan of the 10th Five-Year Plan and the 11th Five-Year Plan. In 2011, China's aluminum processing materials output reached 2,345.58 million tons, with a growth rate of 20.58%; copper production was 10.18 million tons, with a growth rate of 17.57%. It can be seen that although the 2008 financial crisis has produced for China's copper and aluminum processing industry. Certainly, but at present, China's copper and aluminum processing industry has basically got rid of its influence and entered the track of stable development. This fully shows that the central government's policy of stimulating domestic demand is correct, and it is not difficult to see that there is still much room for development in China's domestic market. At present, the growth rate of China's copper and aluminum processing capacity is not decreasing, and fixed asset investment is still strong. Relevant statistics show that during the “Eleventh Five-Year Plan†period, the non-ferrous metal processing industry has completed a total investment of 370.15 billion yuan in fixed assets, with an average annual growth rate of 43.9%. In 2011, the “12th Five-Year Plan†started with an investment of 162.25 billion yuan. In 2005, it was 7.8 times that of 20.68 billion yuan. At present, there are nearly 100 large and medium-sized aluminum processing projects under construction, with a total investment of nearly 200 billion yuan, including more than 50 aluminum flat rolling projects under construction, with a total investment of more than 110 billion yuan. More than 40 aluminum extrusion projects are under construction. Invested more than 80 billion yuan. During the “Twelfth Five-Year Plan†period, the copper processing capacity was 3.15 million tons. Among them, copper wire rods and wire rods are about 1.5 million tons, tube rod profiles are about 450,000 tons, and copper strips are about 1.2 million tons. However, while seeing the results, it should also be recognized that the gap between China's copper and aluminum processing industry and the world's advanced level still exists, and the development bottleneck is still restricting industrial development. In terms of equipment level, industrialization technology and high-precision product research and development, China has a clear gap with the world's advanced level. For example, in terms of equipment, multi-roll mills for processing more than 6 rolls of high-precision copper strips cannot be produced in China; in terms of industrialization technology, China is still mainly based on tracking, imitation, and introduction of technology, and truly independent. There are few technologies for intellectual property rights; for high-precision products, high-quality oxygen-free copper, cable belts, transformer belts, lead frame strips, and rolled copper foils in the copper industry for the electronics industry can be produced, but the quality is unstable and the reliability is poor. Since the cornerstone of industrial technology upgrades from where the "Eleventh Five-Year", China's copper and aluminum processing industry after years of development, has made gratifying achievements in technology and equipment has a number of scientific and technological achievements. For example, high-speed railway nickel-silver bronze material, copper alloy pipe high-efficiency, low-consumption continuous manufacturing technology, aluminum liquid online degassing technology and equipment applied to aluminum alloy green solution, development of aluminum alloy material for national defense military industry, large aluminum alloy extrusion Research and development and production applications of press tools. At present, China's copper and aluminum processing materials are developing in the direction of high precision, high performance, energy saving and environmental protection. The proportion of high-precision sheet and foil and industrial aluminum profiles is increasing, and the direct casting slab and short-flow continuous casting and rolling process of electrolytic aluminum liquid with obvious energy saving and emission reduction effects are being promoted. This series of achievements has laid the foundation for the sound and rapid development of China's copper and aluminum processing industry. Throughout the non-ferrous metal industry, the non-ferrous metal processing industry is the last link of the entire non-ferrous metal industry, as well as the concentrated expression of technology, equipment and product levels, closely related to the development of the national economy. With the development of the national economy, high-strength and high-conductivity copper alloy, high-purity oxygen-free copper, high-precision and high-surface-quality copper alloy materials, high-performance and high-formity automobile body aluminum alloy, aluminum tank car aluminum alloy, high-precision large aluminum Alloy profiles and products such as aviation and marine aluminum alloys are becoming more and more competitive. This requires enterprises to strive to improve their technical equipment and produce highly competitive products that the market needs in the production process. Enterprises are the mainstay of innovation, and technology investment is the essential condition for enterprise innovation, technological advancement and industrial upgrading. In the process of industrial transformation, enterprises to increase investment in science and technology will effectively promote the improvement of their own competitiveness, and will also promote the scientific and technological progress of the non-ferrous metal processing industry and lay a solid foundation for the sustainable development of the non-ferrous metal processing industry. Precise positioning market layout according to According to incomplete statistics, "five-second" period, China in the construction of copper, aluminum production capacity of 315 million tons and 14 million tons respectively, after the completion of all, China's copper, aluminum capacity utilization The rate will drop to 85% and 80%. It is worth noting that although the production capacity of copper and aluminum processed materials in China has increased year by year, the added value of its products is low, the profit rate of enterprises is not high, and high-end copper and aluminum processed materials still rely on imports. It can be seen that China's copper and aluminum processing materials are currently highly competitive in the homogenization of medium and low-end products. According to market demand, rational industrial layout is particularly important. Taking the aluminum processing industry as an example, the layout planning of the aluminum processing industry must conform to the development law of the aluminum industry and the actual national conditions of China. After more than 60 years of development in China's aluminum processing industry, due to the market factors, the eastern coastal area has formed a pattern of development of aluminum processing and deep processing, supplemented by electrolytic aluminum. Due to the resources (bauxite, coal-electricity) factors, the central and western regions have formed a pattern of development of electrolytic aluminum and aluminum processing. However, in recent years, while the western region has developed electrolytic aluminum at a high speed, aluminum processing projects have also experienced unprecedented development. Most of the projects are in the stage of construction and construction. In this regard, industry experts said that most of China's copper and aluminum processing materials are in surplus or about to be surplus, the new economic growth point of copper and aluminum processing industry should be in high-precision products and new products, so if the western region is large-scale The development of products in the east that are already or will be surplus, it is difficult to compete with the eastern enterprises for the market, which will certainly damage the western enterprises themselves, and will also increase the overcapacity in the domestic market. The healthy and sustainable development of the domestic non-ferrous metal processing industry depends on the rational layout of the eastern and western industries. According to the current economic environment and development of the eastern and western regions, the industry believes that, first of all, the western region is more suitable to use resources and energy advantages, develop products such as aluminum processing billets, and gradually establish a stable market in the east. Upstream and downstream supply relationships. Secondly, the western region is suitable to transfer technology, production capacity and market in the eastern region in the form of capital cooperation, and develop civilian aluminum materials that can be consumed in the region. For example, in the process of economic development in the western region, urban construction and real estate projects will inevitably rise rapidly, and the copper and aluminum materials for construction will be considerable. Therefore, the appropriate construction of copper and aluminum projects for construction can support the development of western processing industry and meet local conditions. The construction needs can reduce the excessive expansion of domestic general product capacity. Third, the West can engage in appropriate high-precision product development, but it should not be universal. Therefore, the domestic copper and aluminum processing industry relies on the upgrading of industrial technology to achieve high-precision development of products through industrial transformation. In terms of industrial layout, it should be reasonably configured according to local market conditions, resources and energy.
