Aluminum Corp of China, known as Chalco, said on Thursday it would implement "flexible production", a phrase used to refer to output cuts, at three alumina production lines accounting for about 10% of its total capacity.
Chalco is the world’s biggest supplier of alumina, the substance used to make aluminum, with an annual capacity of 18.86-million tonnes, according to its annual report, which adds that it produced 13.8-million tonnes in 2019.
The three lines, at subsidiaries Shanxi Huaxing and Shanxi New Material in northern China’s Shanxi province, have a combined capacity of 1.8 million tonnes per year, state-run Chalco said in a Shanghai Stock Exchange filing.
