Much of the company’s innovation is happening at the Davenport Works plant in Riverdale, Iowa, pictured here. Home to Alcoa’s 220-inch-wide aluminum rolling mill–the widest such mill in the world–the factory is at the center of Alcoa’s $4 billion aerospace operations, producing metal used in the Airbus A380, the Boeing 777, and other major aircraft. Alcoa AA recently invested $300 million in Davenport over two years to expand its automotive capacity. The company estimates that greater use of aluminum sheet metal by the automotive industry will drive $1.3 billion in revenues for Alcoa by 2018.
