Aluminum Seen Falling Another 11% as China Boosts Supply: Chart

That's the conclusion of researcher Harbor Intelligence, which predicts China will produce about 39 million metric tons by 2020, a more than 75 percent increase from 2010. It's a scenario that casts a shadow over what's left of the U.S. smelting industry.
