Aleris to Expand in China

BEACHWOOD, Ohio, September 27, 2010 - Aleris International, Inc. announced today that it plans to expand
capacity at its Tianjin, China facility by installing a 28MN extrusion press
that will help the company meet increasing demand in China and better serve
its customers that have operations in China. Increased production is expected
to begin in the first half of 2011.

The 28MN press, which is being transferred from Aleris's operations in
Duffel, Belgium, will enable the Tianjin plant to produce nearly three times
its current volume of extrusions by 2015. The press also will broaden the
range of value-added products that can be produced for Aleris customers in a
variety of industry segments.

"Aleris plans to significantly increase local production and capability
in China," said Roeland Baan, CEO, Aleris Europe, and the Aleris executive
responsible for the company's operations in Asia. "Moving this press to
Tianjin is a first step in that process."

The Tianjin facility serves customers primarily in the automotive,
transportation, mechanical and engineering industries. Aleris acquired the
Tianjin plant in 2007, which was first established in 2000 as a joint venture
of Corus Aluminum Vogt GmbH and Tianjin Non-Ferrous Metals Group Co., Ltd., a
state-owned enterprise of China.
