BEIJING - The Aluminum Corporation of China Ltd. (Chalco), the listed arm of the country's largest maker of lightweight metal, said it made net profits of 948 million yuan ($154.87 million) in 2013, reversing heavy losses in 2012.

Total revenues last year hit 173.04 billion yuan, up 16 percent year-on-year, according to the company's unaudited annual business report filed with the Shanghai Stock Exchange on Saturday.

The company attributed the loss-to-profit transition to better management and control over spending as well as capital operations.

It also said a reduction in costs in the production of aluminium oxide and aluminium electrolyte attributed 530 million yuan of profits.
