September 14, 2009

BEIJING & NEW YORK–A significant milestone was reached today for Alcoa’s (NYSE:AA) growth
in China with the inauguration of Alcoa Bohai sheet business at its
plant in Qinhuangdao, China. Alcoa China now has the capacity to produce
the highest quality aluminum sheet for the printing, transportation,
electronics and packaging industries.

During the inauguration ceremony that took place at the Bohai plant in
Qinhuangdao, Klaus Kleinfeld, Alcoa President and Chief Executive
Officer, said, “I strongly believe that with state-of-the-art global
technical support, Alcoa processes and quality control systems,
outstanding equipment and our seasoned work force, Alcoa Bohai will
produce high quality products that will bring significant benefit and
value to our customers.” Kleinfeld added, “Since this year marks the
60th anniversary of the founding of the People’s Republic of China and
the 30th anniversary of China’s reform, we believe that this is a good
time to be launching this important Alcoa business.”

Mr. Ma Yu Feng, the Deputy Executive Mayor of Qinhuangdao Municipal City
expressed his confidence in Alcoa during the ceremony, “Evidence shows
that in 2005 Alcoa’s decision to invest in Qinhuangdao city was correct.
I believe that Alcoa Bohai will maintain its sustainable development in
our city. In the meantime, we hope Alcoa and Mr. Kleinfeld continue to
strengthen the cooperation with Qinhuangdao and, therefore, make it the
closest partner and most reliable friend of Alcoa in China. ”

Equipped with one 1+3 hot mill line, one cold mill, one lithographic
sheet line with one slitter plus a series of finishing equipment, Alcoa
Bohai will enable China to produce the highest quality aluminum sheet,
such as printing industry-use digital plate stocks, hard alloy
transportation sheet, high surface-quality sheet for the electronics
industry, and can body stock.

The newly installed lithographic sheet line is the world’s most
sophisticated and hi-tech line with high quality standard. As the
largest domestic supplier of lithographic sheet, Alcoa Bohai will help
China to replace most of its overseas imports of lithographic sheets and
strengthen its position in advanced lithographic sheet manufacturing and
management.
