Project introduction:

In China, there are 600,000 tons of waste aviation aluminum materials each year. Most of them are utilized as low-end deformed or cast aluminum alloy, which wastes their resource value. Meanwhile, China's aviation aluminum materials are restricted by foreign countries. In this project, the waste aviation aluminum materials were treated as raw materials to manufacture recycled aviation aluminum alloy in a green way for the first time. Waste aviation aluminum alloy was recycled into the original aviation aluminum alloy. The recycled aviation aluminum alloy technology was established with independent intellectual property and standard system. Over the last 12 years, the key technologies on recycled aviation aluminum alloy were broken through and industrialized in our project, including fine separation, green melting, melt deep purification and aviation aluminum materials processing. The products were applied in AVIC, COMAC, Boeing and Airbus etc. The project broke the blockade of developed countries on aviation aluminum alloy and led the development of recycled aviation aluminum alloy in the world. The project had won 1 Japanese patent, 3 American patents, 77 Chinese invention patents, 28 utility model patents and 1 software copyright soft copyright. The project had applied for 2 PCT patents and 7 US, European, Canada and Brazil patents. As chief or a key editor, we had participated in the compilation of 30 national standards, 1 national military standard and 14 industrial standards. The project had published 5 monographs. In addition, the project was rated as ‘international leading level’ by China Nonferrous Metals Association, and won the second prize of National Technological Invention in 2018, the first prize of China Nonferrous Invention in 2020, the silver Prize of China Patent in 2020, the first prize of National Nonferrous Metals Standards Committee in 2020, and the first prize of China Nonferrous Science and Technology in 2016.
