The Aluminum Corp of China (Chinalco), the country's top aluminum producer, said on Thursday its sales revenue reached 142 billion yuan ($21 billion) last year.
The company has yet released its profit figures. Sales revenue was 126 billion yuan in 2008.
Chinalco said its business operation was at a steady running despite the international financial crisis.
The company also made what it said "substantial" progress in business restructuring, including eliminating outdated and highly energy-consuming production capacities.
Chinalco closed six inefficient electrolytic aluminium production lines in 2009. The corporation also saved a total of 1.63 million tons of standard coal.
