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 Continuous Rolling Production Line achieved mass production this year, and the products were successively applied in batches in Shanghai, Guangzhou and Qingdao. Southwest China took the lead in the development of can strips and strips from 0.42 mm to 0.285 mm, 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 and strip, which can produce 3.5 meters wide hot rolled plate, ended the long history of China's super-large, ultra-high-performance aluminum alloy materials imported, and to upgrade the national defense industry Strength and ensuring national security have major practical significance and far-reaching historical significance. A major breakthrough was made in the production of 0.005 mm aluminum foil in China. Yunnan Xinmei Aluminum Foil Co., Ltd. independently developed the “Technology Development of 0.005 mm Aluminum Foil for Billet Production†and Zhengzhou Aluminum produced 0.005 mm 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 with cast blanks is the first in the world. The aluminum foil technical index has reached or surpassed the level of similar foreign products. It has realized the substitution of imports and promoted the miniaturization and weight reduction of domestic electronic components. It is in line with the comprehensive utilization of national resources and construction savings. The requirements of the type of society are of great significance to the technological advancement of the industry and the adjustment of the industrial structure.
