Century Aluminum Company
When the aluminum century rolls around, it'll be ready. Century Aluminum makes primary molten and ingot aluminum at facilities in Kentucky and West Virginia, as well as in Iceland; that last facility is operated by subsidiary Nordural. Century Aluminum also owns just less than 50% of an aluminum production facility in South Carolina (Alcoa owns the rest). Four customers -- aluminum producer Rio Tinto Alcan, diversified metals company BHP Billiton, commodities trader Glencore International, and wire and cable maker Southwire -- account for about three-quarters of Century Aluminum's sales. Glencore is Century Aluminum's former parent, though it still has a 38% stake in the company.
