Not only cars, but also in the entire transportation equipment industry including railway transportation, ocean transportation, aviation, etc., aluminum alloy materials with light weight, excellent performance and recyclability have shown their great advantages. This year, in the three-day “China Transportation Aluminum Exhibition” held in Chongqing, aluminum for transportation has become the biggest bright spot. Its popularity shows that aluminum for transportation has become a new economic growth pole for the aluminum industry.

At present, China's total railway mileage has reached 112,000 kilometers, and large-scale infrastructure investment continues. In pursuit of greater economic benefits, the requirements for vehicle weight are getting higher and higher. The goals of large transportation volume, low cost, energy saving and environmental protection have become the first choice for comprehensive transportation development in China. Everything that steel can do, lighter and harder aluminum can be done almost even better. Therefore, with the light weight and good oxidation and corrosion resistance, the application of aluminum alloy in railway transportation has been rapidly developed.

In July last year, led by Haotong Group, the joint research and development of key technologies for aluminum alloy body materials for rail transit jointly undertaken by Hunan University, Chuangyuan Aluminum and CSR Zhuzhou was based on the application of rail transit lightweight market. As a guide. The 6th Guangdong Aluminum Processing Technology (International) Symposium to be held in November this year is also focusing on the aluminum profile production and supporting industries, highlighting the theme of “transportation aluminum”, with a view to promoting the integration of the transportation industry and the aluminum processing industry. Promote the lightweight process to provide a strong impetus for the adjustment of the industrial structure of China's aluminum processing industry.

In addition, aluminum alloys are also widely used in the aerospace industry because of their high strength, plasticity, impact toughness, fatigue properties and weldability. Aluminum alloys are mainly used as structural materials on aircraft, such as skins, frames, propellers, fuel tanks, siding and landing gear pillars. A set of data shows that in the structure of modern aircraft, 1500-2000 kinds are used. Aluminum castings. Even the fuel tanks, oxidizer tanks, compartment sections, interstage sections, tail sections and instrument compartments of the Saturn 5 launch vehicle that launches the Apollo spacecraft are made of aluminum alloy.
