Aluminum oxide is produced from bauxite, and aluminum oxide is extracted into metal aluminum through electrolysis, which is called primary aluminum or electrolytic aluminum. Aluminum has good recycling performance, and recycled aluminum can be obtained by recycling and smelting scrap aluminum. Both primary and secondary aluminium are used in the production of aluminium alloys and processed into various types of aluminium and aluminium castings. The processing methods of aluminum materials include rolling, extrusion, drawing, forging, casting, etc., to produce various aluminum alloy products with different properties and uses, such as aluminum sheets, strips, foils, aluminum extrusions, and aluminum castings. Energy consumption is the core competitive point of primary aluminum production. The production of primary aluminum usually adopts cryolite-alumina molten salt electrolysis method. The technical principle is relatively mature, but whether it can reduce the consumption of electricity and raw materials per ton of aluminum through technological improvement to control the production cost and reduce the impurity content in the product is the competitive advantage of the enterprise. In addition to energy consumption, impurities are also the key points of competition in electrolytic aluminum production. High-purity aluminum has higher requirements on products and technologies. On the basis of primary aluminum production, the aluminum content can be further increased. It can be used in aerospace, information equipment, military industry and other fields. high technical barriers.

The extension of the industrial chain broadens the long-term growth space of electrolytic aluminum enterprises, and the layout of the entire industrial chain creates a long-term moat. The more complete the industry chain is, the less the profit is affected by cyclical fluctuations, and the product variety and added value are improved, and the profit stability is higher. Extending the industrial chain is the long-term development trend of electrolytic aluminum enterprises. On the one hand, by deploying upstream mines and alumina, electrolytic aluminum enterprises can effectively cope with the dilemma of the gradual depletion of China's bauxite resources; With the adjustment of export policy, the export of electrolytic aluminum is subject to a 15% export tax, while aluminum processed products enjoy export tax rebates. The downward extension of electrolytic aluminum enterprises can not only fully enjoy the price difference between domestic and foreign electrolytic aluminum, but also open up long-term growth space.
