Aleris was established in 2004, and expanded via acquisitions during its early history. The company acquired
Corus Group's aluminum
extrusion and rolling businesses for approximately $894 million (€700 million) in 2006, and Wabash Alloys for an undisclosed amount in 2007. The

Great Recession caused significant downturns in production, and Aleris experienced a 40 percent volume decline during 2008–2009. Aleris stabilized its financial position and significantly reduced debt. The company also invested in its facilities, building a new aerospace plate mill in China during the early 2010s, finishing a $70 million expansion of its facility in
Duffel Belgium (2013), and improving its plant in
Ashville, Ohio, in 2014. The aluminum finishing plant in Decatur was closed before the end of the year to streamline operations. Aleris had more than 40 production facilities in North America, Europe, and Asia, as of October 2014.

The divestitures decreased the number of employees to around 5,000.

Greater Cleveland. Aleris' new aluminum body sheet facility in
