At 15:37 on October 31, at the Wenchang Space Launch Site in Hainan, the Long March 5B Yao-4 carrier rocket lifted the Mengtian experimental module, the second experimental module of the Chinese space station, to ignite and take off, and the launch through the clouds and mists lingered into the sky and accurately entered the predetermined orbit. . In the construction of China's space station, a large number of "Southwest Aluminum" high-precision aluminum materials once again shine in space.
As the core base for the research and development of aluminum alloy materials for aerospace in my country, Southwest Aluminum provided more than 80% and more than 60% of the key aluminum for the "Mengtian" experimental module and the Long March 5B Yao-4 launch vehicle respectively in this launch mission. Alloy materials, covering forgings, plates, profiles, pipes and other categories with more than 10 specifications and varieties, are mainly used for the surface structure of the experimental cabin and key parts such as the transition ring, transfer frame, and storage tank of the launch vehicle, and play a role in the skin. , support and connection.

Among them, 100% of the super-large-sized sheets for the skin of the rocket propulsion compartment and the experimental compartment, and 100% of the structural connection forging rings of a certain type are exclusively provided by Southwest Aluminum. These key aluminum alloy materials have the characteristics of high metallurgical quality, high performance technical indicators, many varieties and specifications, and large component sizes. Their manufacturing technology is the most advanced aluminum processing technology in the world today.
The 2xxx alloy super-sized plate used for the low-temperature fuel storage tank of the Long March 5B Yao-4 launch vehicle has a large component size, and the required plate width is more than 2000mm. On the one hand, the performance and internal quality of the sheet are higher than GJB and international standards, on the other hand Source:
