In the first half of this year, China's aluminum processing industry has achieved new progress while maintaining rapid development while advancing scientific and technological progress and promoting industrial upgrading. The ultra-thin aluminum plate produced by the Southwest Aluminum 1+4 hot rolling line has achieved mass production this year, and the products have been applied in batches in Shanghai, Guangzhou and Qingdao. Southwest China took the lead in the development of cans and strips in the country and reduced it from 0.42 mm to 0.285 mm, which is only one step away from the international advanced level of 0.265 mm. Dongbei Light Alloy Co., Ltd. invested 2.99 billion yuan in large-size special aluminum alloy sheet and strip projects and Germany's Demark company formally signed a purchase agreement. The project is an annual output of 200,000 tons of aluminum alloy sheet strip, larger 3.5 meters wide hot-rolled plate production, ended the long history of China's super-large specifications, ultra-high performance aluminum alloy materials imported history, but also to upgrade the defense industry Strength and ensuring national security have major practical significance and far-reaching historical significance. China made a major breakthrough in the production of 0.005mm aluminum foil. Yunnan Xinmei Aluminum Foil Co., Ltd. independently developed the "Technology Development of 0.005mm Aluminum Foil for Billet Production" and Zhengzhou Aluminum produced 0.005mm aluminum foil using all localized equipment. Metal Industry Association and Henan Province Science and Technology Department organization identification. The production of 0.005 mm aluminum foil by casting and rolling stock is the first in the world. The aluminum foil technical index has reached or surpassed the level of similar foreign products, realized the substitution of imports, promoted the miniaturization and weight reduction of domestic electronic components, and was in line with the comprehensive utilization of national resources and construction savings. The requirements of a type of society are of great significance to industrial technological progress and industrial restructuring.
