Introduction to the industry chain of aviation aluminium alloys for sale Haomei

In China, the demand for large aircraft manufacturing is strongly driving the demand for aluminium alloy materials for sale, especially like aviation aluminium alloy, aviation aluminium alloy materials. The C919 large passenger aircraft has already received more than 500 orders from more than 20 international airlines, and the ARJ21-700 has more than 200 orders. According to the plan, by 2018, more than 30% of the aluminium alloy materials used in the ARJ21 regional passenger aircraft and C919 large aircraft will be made in China. The demand for aluminium alloy materials for China's large aircraft has increased the development of China's aviation aluminium alloy research and development and the scale of the industrial chain.

The aluminium industry chain is mainly composed of four links: bauxite mining, alumina refining, primary aluminium production and aluminium processing. Firstly, bauxite is mined, then alumina is refined by dissolving, filtering, acidifying and burning the bauxite, and then electrolytic aluminium is prepared by electrolytic melting. Electrolysed aluminium can be further processed into various aluminium materials, aluminium alloys and aluminium powders after remelting and purification.

Next we look at the downstream analysis of the aviation aluminium alloy industry chain. The downstream industry chain of aviation aluminium alloys is mainly the processing and use of aluminium alloys. Aviation aluminium alloys are mainly deformed aluminium alloys that can be strengthened by heat treatment. Therefore, the downstream processing of aviation aluminium alloys is particularly important. The processing of aluminium alloys for aviation is shown in the diagram below, which includes extrusion, rolling and casting. The downstream applications of processed aluminium alloys for aviation are very diverse and are closely related to industry, transport and the rise in consumption levels. Aluminium alloys for aviation are mainly forgings, rolled sheets and other aluminium profiles. The downstream demand for aviation aluminium alloy is mainly in the transportation industry, especially in the manufacture of aircraft and missiles in the aerospace and defence sectors.

In recent years, with the development of China's large aircraft industry and rail transportation industry, the downstream processing industry of aviation aluminium alloy will usher in a faster development stage, and the consumption of aviation aluminium profiles in China will maintain a high growth rate.
