With the continuous expansion of aluminum alloy applications in various fields, the requirements for its surface performance are increasingly higher. Recently, a series of new aluminum alloy surface treatment methods have been launched. For example, the adoption of advanced pulse anodizing technology can form a more uniform and dense oxide film on the aluminum alloy surface, significantly enhancing its corrosion resistance and wear resistance; there is also an innovative laser surface treatment process that can accurately change the micro-structure of the aluminum alloy surface, improving surface hardness while endowing the material with special optical or electrical properties. These new methods provide a more solid guarantee for the application of aluminum alloy products in harsh environments such as aerospace and marine engineering, and are expected to reshape the pattern of the aluminum alloy surface treatment market.

Affected by the trend of automotive lightweight and the rapid rise of the new energy vehicle industry, aluminum alloy parts are being increasingly widely used in automobile manufacturing. In order to reduce vehicle weight and improve cruising range, automakers have seen explosive growth in demand for aluminum alloy parts such as anti-collision beams, body structural parts, and battery trays. This trend has prompted aluminum alloy manufacturers to strengthen in-depth cooperation with auto parts suppliers, forming a whole-industry-chain collaborative innovation model covering material R&D, product design, and large-scale production. It is expected that in the next few years, the market scale of aluminum alloy auto parts will grow at an annual rate of 20% - 25%, driving the accelerated upgrading of the entire aluminum alloy industry.

Recently, a major breakthrough has been achieved in the aluminum alloy processing field. An enterprise has successfully developed a new type of extrusion process, which significantly improves the production efficiency and quality of aluminum alloy profiles by optimizing mold design and extrusion parameters. It is reported that the new process can realize the forming of more complex profile structures while reducing material waste. Industry experts stated that this innovation will promote the wider application of aluminum alloy products in construction, automotive, electronics, and other industries. It is expected that within the next two years, the overall industry capacity will increase by 15% - 20% due to similar technological innovations, strongly driving the aluminum alloy industry towards high-end development.
