Since the 12th Five Year Plan, Chalco has made rapid progress in science, technology and innovatio🌱n, and achieved a variety of important results, thanks to concerted efforts of R&D staff of Chalco. Some of these results have been applied to production, and have produced remarkable economic and social benefits, contributing to the development of Chalco and the whole industry. Meanwhile, the company has met with technicaꦗl difficulties that impede itself and the industry. Now Chalco has released some of its proprietary technologies and S&T demands, in the hope of making greater contribution to China’s aluminum industry by collaborating with all sectors of the community on S&T difficulties.
