Answer: Alcoa, Inc.
Alcoa, Inc. (from ALuminum Company Of America) is the world's third largest producer of aluminum, behind Rio Tinto Alcan and Rusal. From its operational headquarters in Pittsburgh, Pennsylvania, Alcoa conducts operations in 44 countries. In May 2007 Alcoa made a $27 billion hostile takeover bid for Alcan, a former subsidiary, aiming to unite the two companies and form the world's largest aluminum producer. The takeover bid was withdrawn after Alcan announced a friendly takeover by Rio Tinto in July 2007.
Among Alcoa's other businesses are fastening systems, building products (Kawneer), Howmet Castings, and electrical distribution systems for cars. The sale of the packaging unit was announced on December 21, 2007 and closed in the first quarter of 2008.
