Aluminum processing is to use plastic processing method to process aluminum ingots into products. The main methods are rolling, extrusion, stretching and forging. The processed products are all kinds of aluminum products produced by plastic deformation process, also known as semi-finished products, i.e. plates, strips, foils, tubes, bars, shapes, wires, forgings, powders and pastes, etc. for users to manufacture aluminum products.

In 2019, the output of raw aluminum and aluminum products in China is relatively high, with the output of aluminum products reaching 52.52 million tons, with a cumulative increase of 7.5% over the same period of last year, and the output of raw aluminum will reach 35.044 million tons. From January to may 2020, the output of aluminum products will be 20.951 million tons, with a cumulative year-on-year increase of 4.9%.

From the perspective of regional distribution of aluminum production, Shandong Province and Henan Province will rank the top two in terms of aluminum production from January to may 2020, with the aluminum output reaching 4.449 million tons and 3.3923 million tons respectively, followed by Guangdong Province with the output of 2226200 tons.

From the regional concentration of aluminum production, the regional distribution of aluminum production in China is relatively concentrated. From January to may 2020, Shandong, Henan and Guangdong, the top three aluminum products, accounted for 56%, accounting for 25%, 19% and 12% respectively.

Affected by the distribution of industrial base and downstream manufacturing industry, aluminum processing industry is concentrated in Shandong, Henan, Guangdong and other provinces. Overall, the aluminum market is developing to low cost, high efficiency and low energy consumption. In terms of policy support, Shandong, Henan, Guangdong and other places give policy support to the upgrading of aluminum processing industrial structure. The special plan for the development of new material industry in Shandong Province (2018-2022) points out that it is necessary to accelerate the formation of an industrial chain of "energy alumina electrolytic aluminum aluminum processing aluminum intensive processing" relying on the three aluminum industry clusters of Yantai, Binzhou and Liaocheng. Aiming at the supply of medium and high-end aluminum profile products in the fields of automobile, aerospace, consumer electronics, electric power equipment, rail transit equipment, etc., to create an important aluminum industry cluster and innovation highland at home and abroad. Henan and Guangdong have also issued aluminum industry upgrading plans to promote the upgrading of aluminum processing industry structure.

Shandong, Henan and Guangdong have multiple factors to maintain the leading position of aluminum production in China all year round. Shandong has a solid aluminum industry foundation and complete upstream and downstream industrial chain. However, Shandong itself is a big province of heavy industry in China, where high pollution industries are concentrated and environmental protection problems are serious. In the future, production capacity may be gradually transferred to other provinces. Henan has a superior geographical location, rich in bauxite and coal resources, but its electricity cost is high and environmental protection pressure is also great. Guangdong is one of the important bases of nonferrous metal industry in China. It is not only a big province of aluminum processing material production, but also a big province of aluminum consumption. However, the product structure still needs to be optimized, and the product homogenization competition pressure is great; the technology and process of medium and high-end products still need to be strengthened research and development.
