1. Implement energy conservation and emission reduction.
By adopting advanced and suitable new cathode structural aluminum electrolysis technology, advanced and efficient alumina energy-saving technology, and cutting-edge aluminum processing technologies, we will carry out technological upgrades to the existing capacities for primary aluminum smelting, alumina production, and aluminum processing. This will enhance the industry’s technological equipment level, reduce material and energy consumption, expand product variety, and improve product quality.
II. Develop high-precision products
Relying on leading enterprises, industrial clusters, and major projects, we will actively promote the industrialization of new technologies and their large-scale manufacturing. Key areas of development include medium- and thick-sized aluminum alloy plates for aerospace applications, high-performance aluminum alloy semi-solid billets and components, materials for turbine engine impellers, 6-series automotive aluminum alloy sheets, 2-series aluminum alloys, 7-series aluminum alloys, aluminum-lithium alloys, aluminum alloy plates for cryogenic equipment, large-scale aluminum profiles for high-speed and freight trains, weldable aluminum alloy thin sheets, ultra-high-purity aluminum, high-pressure anodic aluminum foil, and advanced deep-processing products.
III. Developing Aluminum Ore Resources
By exploring and developing both domestic and overseas resources, we can effectively increase domestic resource reserves and the volume of equity-based resources abroad. We will accelerate the development of overseas aluminum ore supply bases to ease pressure on domestic aluminum ore supplies, break the international monopoly on aluminum ore resources, address bottlenecks in aluminum ore supply, and ensure the sustainable development of China’s aluminum industry.
IV. Promote the Circular Economy
Following the principles of the circular economy and promoting clean production, we will control pollutant generation and emissions at the source and throughout the entire process, thereby reducing resource consumption. We will strengthen the comprehensive utilization of red mud, spent lining from electrolytic cells, and high-aluminum coal resources, thus elevating the level of integrated resource utilization. We will also improve the recycling system for renewable resources and advance the large-scale, efficient utilization of these resources.
V. Implement the “Going Global” Strategy
The primary resources—such as bauxite and coal—that support the aluminum industry are characterized by scarcity or non-renewability. Consequently, strategic competition and control will undoubtedly focus on aspects such as the reserve accumulation, integration, allocation, orderly development, and efficient utilization of these strategic resources. Given the domestic shortage of resources, the increasingly fierce and saturated nature of the domestic market, and the growing need to diversify, it is imperative to implement a “go global” strategy. We should target countries and regions that currently face no policy restrictions, have relatively underdeveloped production technologies, and boast abundant bauxite resources. By directly or indirectly gaining control over their bauxite reserves, we can expand into overseas markets through establishing factories abroad or adopting an EPC general contracting approach.
6. Accelerated innovation, product upgrades
According to the “12th Five-Year Plan” for the aluminum industry, by the end of the 12th Five-Year Plan period, the comprehensive electricity consumption per ton of aluminum ingot should be reduced to below 13,300 kilowatt-hours. Under the dual pressure of daunting energy-saving and emission-reduction tasks and intense competition driven by low costs, technological innovation in the aluminum industry is poised to reach a new peak of development. Looking ahead, the main directions of technological innovation will focus on the following areas: low-carbon, low-energy-consumption, low-pollution, long-life, and highly efficient green smelting technologies; localization and intelligentization of key aluminum equipment; the circular and efficient utilization of intermediate products, by-products, and waste from aluminum production; and the industrialization of bauxite substitutes as well as the development of high-strength, high-damage-tolerance aluminum alloy materials.
