China's aluminum plate industry

Driven by the 'dual carbon' strategy and high-end manufacturing, China's aluminum plate industry has achieved a qualitative change from 'scale expansion' to 'value enhancement' through four innovation engines: material research and development, process innovation, intelligent manufacturing, and green low-carbon, fully empowering key fields such as new energy, aerospace, and automobiles. In terms of material innovation, domestic brands such as Chinalco 6B05 automotive aluminum plate have broken foreign monopolies, 7050 aviation alloy and 8A63 new energy special alloy have achieved performance breakthroughs, and the localization rate of high-end products has increased to 60%. In terms of technological breakthroughs, Jiugang successfully rolled 0.05mm ultra-thin aluminum plates, Nanshan Aluminum's wide width and high processing rate aluminum foil technology drove the upgrade of double zero foil, and the 'speed tension' linkage control overcame the problem of high-precision rolling. Intelligent manufacturing is accelerating its implementation, with an AI surface defect inspection accuracy rate of over 95%. A single operator can monitor 10 production lines, and the aluminum template intelligent production line can produce a finished product in 75 seconds, increasing efficiency by three times. The green and low-carbon innovation has achieved significant results. The closed-loop of 'photovoltaic+energy storage+intelligent production' has reduced unit energy consumption by 15%. The aluminum ash resource utilization technology has achieved zero solid waste emissions. The hydropower aluminum process has reduced the electricity consumption per ton of aluminum to 13250 kilowatt hours. The industry university research cooperation builds a full chain innovation system, and Southwest Aluminum provides nearly a thousand tons of materials for C919, promoting the industry from 'following' to 'leading' and becoming the core material support for high-end manufacturing.
