In the recently held annual working conference on the upstream and downstream cooperation mechanism of civil aircraft Aluminum materials, CAAC, China Commercial Aircraft, China Aviation Industry Corporation, China Aluminum Corporation, Nanshan Aluminum and other units reported on the application and development of civil aircraft aluminum and related Suggest. The Ministry of Industry and Information Technology must work out a key work plan for 2017 as soon as possible. Production units should speed up the development and application of key grade aluminum materials in order to achieve breakthrough progress in 2017 and lay a solid foundation for the development of China's aerospace industry.

Today, with the increasing development of air transport, people are already very familiar with flying, and it can be said that it is one of many travel modes. Aluminum has always been a key structural material in the aviation industry. From the point of view of data, at present, the main civil aircraft in the world, the amount of aluminum used is more than 70%, so the research and development of new aircraft will require more high-quality aluminum. China's "Long March" series carrier rockets and the "Shenzhou" series of spacecraft's fuel tanks, manned cabins, orbital modules, and the Tiangong-2 space laboratory's resource and experimental chambers all require large amounts of aluminum. High-strength aluminum materials have very good performance specifications, and their strength, plasticity, impact toughness, fatigue properties, and weldability are all excellent. Therefore, in addition to aerospace, aluminum materials are often used in construction. Industry and other popular transportation tools. For example, in rail transportation, aluminum profiles and aluminum plates have become the main material of the body of rail vehicles. The development of aluminum will also promote the development of cities in our country. Obviously this is complementary.

According to the prediction of China Aviation Industry Corporation, by the year 2025, the number of domestic air transport aircraft will reach 3,900, of which 2,000 will be large passenger planes, which will make China the world’s second largest aviation market after the United States. With the rapid development of aircraft manufacturing in China, aviation aluminum market demand will usher in a substantial expansion. At present, most of the aircraft manufacturing parts of China’s airlines rely on foreign imports. To a large extent, they distrust the quality of local aluminum materials. Therefore, improving the quality of aluminum materials will also be a major goal of the aluminum industry this year, and then realize aluminum materials. Fully localized. It is worth mentioning that after many years of unremitting efforts, Chinalco and Southwestern Aluminum have made breakthroughs in various technological difficulties. At the end of December 2016, it successfully achieved large-scale production of high-strength and high-toughness 7050 aluminum alloy thick plates. Aluminum alloy pre-stretched thick plate is a high-tech and high value-added product, which positively reflects the ever-changing aerospace aluminum technology in China, and the gap between Europe and the United States and other developed countries is gradually reducing, but the technology is not yet leading, aluminum downstream Industry still needs to work hard.

Last year, the electrolytic aluminum production capacity in the upper reaches was significant. At the end of the year, it successfully fought a turnaround. As a result of preliminary calculations, Chinalco, a listed company of Chinalco, expects the total profit realized in 2016 to be approximately RMB 1.6 billion, which is an increase of approximately 7.3 times compared with that in 15 years. This is the first time that Chinalco has realized operating profitability since commodities entered the down cycle in 2011. It is indeed gratifying. This fully demonstrates the staged victory of the supply-side reform, and it also reveals the necessity: Upstream elimination of excess capacity can enable the aluminum industry to focus on the construction and development of downstream high-end industrial chains. Taking Chinalco as an example, he signed cooperation agreements with several domestic large-scale central enterprises and well-known private enterprises, including aluminum communication towers, aluminum overpasses, aluminum formworks, aluminum integrated houses, construction aluminum climbing frames, and mobile phone cases. Dozens of products such as alloys, auto parts and aluminum flood protection walls. Earlier last year, Chinalco participated in the 11th China International Aerospace Exhibition and signed a strategic cooperation agreement with China Aerospace Science and Technology Corporation. They will conduct in-depth cooperation in the research and development of aerospace materials, energy conservation and environmental protection as well as personnel training.

On the one hand, the improvement of technology and successful transformation are exciting news, and on the other hand, we cannot ignore the environmental protection issues in the production of aluminum industry. During the Spring Festival, the Beijing-Tianjin-Wing and the surrounding areas suffered severe haze. According to sources, although the production of SMEs has decreased, many large companies have not stopped production. For example, because of the strong market demand for electrolytic aluminum, some companies may have to work overtime to increase production, which leads to the fact that the discharge of pollutants has not fallen due to holidays. In addition to demand, the reduction in the cost of production of electrolytic aluminum is likely to prompt a resumption of production. The aluminum products produced by the remanufactured aluminum plant will not be affected by the environmental protection and low-cost rough technology and will inevitably affect the downstream aluminum industry quality. This kind of behavior that affects the environment and violates the 13th Five-Year Plan should be eliminated. Foshan Environmental Protection Bureau also issued and rectified more than 100 local air pollution aluminum factories in March last year. "The people who don't want to be changed are not allowed to enter," and the progress of the green environmental protection program must be difficult to advance and seek change. Relevant departments in China need to reiterate and emphasize that aluminum upstream and downstream industries are closely linked; upstream production will affect the progress of R&D and production of downstream high-end aluminum materials, which in turn delays the optimistic outlook for the vigorous development of China's aerospace industry.

Undoubtedly, as an aerospace industry's indispensable and lightweight materials, the development of aluminum materials will lead a new era. As the civil aluminum working conference stated, the upstream and downstream cooperation mechanism of the aluminum industry is the most effective way for the market to promote collaborative aviation aluminum research. The aluminum industry must make concerted efforts to make every effort to create a brilliant contribution to China's aerospace industry. After the new year, the 2017 Year of the Rooster will set off again, allowing the aluminum industry to help build China's aerospace industry and achieve better results!
