Aerospace industry has become an important development direction of aluminum processing downstream
Nov 11, 2017

With the rapid development of air transport, people are very familiar with the flight, it can be said to be a variety of ways of travel. Aluminum has been a key structural material in aviation industry, from the data point of view, the current major civil aircraft in the world, the amount of aluminum in more than 70%, so the development of new aircraft will need high-quality aluminum. A large number of aluminum materials are needed for the fuel tanks, manned cabins, orbital modules and the space capsule and the experimental cabin of the two space laboratory in China's "Long March" series of launch vehicles and "Shenzhou" series of spacecraft propulsion capsule. High strength aluminum material has very good performance indicators, and its strength, plasticity, impact toughness, fatigue properties and weldability are all very good; therefore, in addition to aerospace, aluminum is also often used in the construction industry and other public transport tools. For example, aluminum and aluminum have become the main body of rail vehicle body in rail transit. The development of aluminum materials will also promote the urban development and construction of our country. Obviously, this is complementary to each other.

.

According to China's Aviation Industry Corp forecast, by 2025, the number of domestic air transport aircraft will reach 3900, of which large passenger aircraft will reach 2000, which will make China the next to the United States the world's second largest aviation market. With the rapid development of aircraft manufacturing in our country, aviation aluminum market demand will usher in a substantial expansion. At present, most of the materials of aircraft manufacturing parts of our country rely on foreign imports, largely to the quality of the local aluminum material distrust, so improving the quality of aluminum materials will also be a major goal of this year's aluminum industry, and then to achieve full localization of aluminum. It is worth mentioning is that the aluminum and SWA after years of unremittingly efforts, through various technical difficulties, at the end of December 2016 the successful implementation of the high strength and high toughness 7050 Aluminum Alloy plate scale production. Aluminum alloy pre stretched thick plate is a high-tech product with high added value, which reflects the rapid development of China's aerospace aluminum technology, and the gap between developed countries such as Europe and the United States is gradually reduced, but the technology has not yet led, aluminum downstream industry still need to work hard.

Last year, the electrolytic aluminum production capacity of the upper reaches of the effect of significant, at the end of the year successfully created a turnaround campaign. The preliminary calculation results show that the total profit of China Aluminum Corporation, which is listed by Chalco, is expected to reach 1 billion 600 million RMB in 2016, which is about 7.3 times higher than that in 15 years. This is since 2011 commodity into a downward cycle, the aluminum company achieved operating profit for the first time, it is gratifying. This fully reflects the phased victory of the supply side reform, but also points out its necessity: the elimination of excess capacity upstream, in order to allow the aluminum industry to focus on the construction and development of downstream high-end industrial chain. In the aluminum company for example, he and a number of domestic large central enterprises, well-known private enterprises have signed a cooperation agreement involving sales of aluminum, aluminum, aluminum, aluminum communication tower bridge template, aluminum housing, building integrated aluminum alloy shell, climbing frame, mobile phone auto parts, aluminum flood wall and dozens of products. Earlier last year, Chinalco participated in the Eleventh China International Aerospace Exhibition, and signed a strategic cooperation agreement with aerospace technology group. They will make deep cooperation in space materials research and development, energy saving, environmental protection and personnel training.

On the one hand, the upgrading of technology and successful transformation is exciting news, on the other hand, we can not ignore the environmental issues in the production of aluminum industry. During the Spring Festival, the Beijing Tianjin wing and surrounding areas suffered severe haze. The news is that although the production of SMEs is reduced, there are still many large enterprises have not stopped production. Like electrolytic aluminum, some companies may have to work overtime because of the strong demand for the market, which has led to a decline in the amount of pollutants that did not occur during the holidays. In addition to the demand, reduce the production cost of electrolytic aluminum is likely to prompt the resumption of production. The resumption of production of aluminum electrolytic aluminum through environmental protection, low crude technology and produce, will inevitably affect the quality of downstream aluminum industry. This not only affects the environment and violate the "13th Five-Year" policy, should be eliminated. Foshan Environmental Protection Bureau also issued in March last year and remediation of the more than 100 local air pollution aluminum plant. "Not for easy person, do not shelter in" green environmental protection in the reform process to overcome difficulties, to seek change. China's relevant departments need to reiterate and emphasize that the upstream and downstream industries of aluminum are closely related; upstream production will affect the downstream high-end aluminum material development and production schedule, and then delay the optimistic prospects of the booming development of China's aerospace industry.

.

There is no doubt that as a space and aviation industry, there are few toughness and lightweight materials. The development of aluminum materials will usher in a brand new era. As the aircraft aluminum work conference said, the cooperation mechanism of downstream aluminum industry is the most effective way to promote the market of aviation aluminum collaborative research. The aluminum industry should make concerted efforts to better each pass and make a brilliant contribution to the field of aerospace and aviation in china. After the new year, 2017 chicken year departure, let the aluminum industry help China aerospace construction, create new success!
