The main technical development project of high-performance aluminum alloys for direct casting of electrolytic aluminum, which was undertaken by Guizhou Aluminum Plant, was formally launched as a major project in the province during the “11th Five-Year Plan†period. Special funds of 5 million yuan have been allocated.
According to reports, the major project is based on electrolytic primary aluminum direct casting technology and based on the main line, the development of 7050,7075 and civilian high-end aluminum alloy flat ingots, new high-strength casting aluminum alloy and new steel hot dip coating aluminum alloy material, It is of great significance to solve the bottleneck that restricts the development of China's national defense industry and aerospace industry, and to break the monopoly of high-end civilian aluminum alloy materials in foreign countries.
It is understood that the project will rely on the Guizhou Aluminum Plant's annual production of "400,000 tons of electrolytic aluminum and 200,000 tons of aluminum alloy," "100,000 tons of aluminum alloy round ingots," "aluminum products deep processing," and other key projects, through the northeast Light alloy company, Southwest Aluminum, Guihang Group, Central South University, Sichuan University, Guizhou University, Shanghai University, Guiyang Aluminum Magnesium Design and Research Institute, Guizhou Academy of Sciences and other enterprises, universities and research institutes to implement cooperation in production, research, and development of high-performance aluminum The research of alloys and their manufacturing processes has led to the formation of large-scale cast billets and steel plating materials and other production technologies with independent intellectual property rights. The project will focus on solving the key and common technical issues such as composition formula, melting and casting, high-efficiency melt processing, strengthening and toughening technology, trace element alloying technology, and heat treatment technology in the production process of high-performance aluminum alloys, and developing and producing high-end and high-strength products. , high-performance, high value-added aluminum alloy products.
