Aleris Breaks Ground for $300 Million Greenfield Rolling Mill in China

BEACHWOOD, Ohio, January 18, 2011 - Aleris International, Inc. today broke ground for the construction of a
state-of-the-art aluminum rolling mill in China's Zhenjiang City, Jiangsu
Province that will produce semi-finished rolled aluminum products in a joint
venture with Zhenjiang Dingsheng Aluminum Industries Joint-Stock Co., Ltd.
Aleris will own an 81 percent equity interest in the venture, named Aleris
Dingsheng Aluminum (Zhenjiang) Co., Ltd.

The factory will produce rolled aluminum plate, heat-treated plate and
non-heat treated plate for the aerospace, general engineering, tooling and
molding, petrochemical and transportation industries. The company said that
the operation also has the potential to manufacture product for automotive
applications.

"This groundbreaking is a tangible demonstration of our commitment to
serving customers in China," said Steven J. Demetriou, Aleris chairman and
chief executive officer. "We appreciate and value the collaboration with our
partner, Dingsheng, and the support of Jiangsu Province and the City of
Zhenjiang, which have helped make this new industrial venture possible. We
look forward to a long and productive relationship with all involved."

The Aleris-Dingsheng partnership will build and operate one of the most
technologically advanced rolling mills in the world. The potential rolling
force of this hot mill qualifies it as the world's strongest, similar to the
one at Aleris's Koblenz, Germany facility. Additionally, various advanced
commercial plate products developed by Aleris will be produced at the
Zhenjiang facility, providing a range of alloy options for Chinese customers.

The mill is designed for an eventual capacity of approximately 250,000
metric tons, with approximately 100,000 square meters initially under roof,
on more than 280,000 square meters of land. Construction is expected to be
completed within two years, with product shipping to customers by the fourth
quarter of 2012.
