  Alcoa Wins Long-Term Siemens Contract to Supply Blades and Vanes for
  Heavy-Duty Gas Turbines

Business Wire

NEW YORK -- December 20, 2012

Alcoa (NYSE: AA) today announced that Alcoa Power and Propulsion (APP) has
signed a long-term agreement with Siemens Energy to supply blades and vanes
for a wide range of industrial gas turbines. Siemens Energy is one of the
world’s leading suppliers of products, solutions and services in the energy
technology field. Contract terms were not disclosed.

Alcoa parts made in the U.S. and Europe will be used in, among others, the
Siemens F-Class turbine which generates enough power to supply the energy
needs of a city of 300,000 residents.

“Alcoa’s blades and vanes operate in the most demanding section of the
turbine, where temperatures sometimes exceed the melting point of the casting
and the rotational rate exceeds the speed of sound,” said Andreas
Fischer-Ludwig, Director of Global Blades & Vane Business at Siemens Energy.
“But even in that severe environment, Alcoa technology keeps the castings
working optimally, which is crucial to our global customers who need to
generate electricity dependably.”

“We are pleased that Siemens Energy recognizes the value Alcoa’s expertise in
investment casting brings to building efficient and durable power generation
equipment,” said Allen Zwierzchowski, Vice President, APP. “As a global leader
in investment castings, we are well-positioned to support demand for
industrial gas turbines as power suppliers use greater amounts of low-priced
natural gas to produce electricity.”

The Alcoa contract builds upon a 30-year relationship with Siemens and
provides the opportunity to collaborate on technology to further improve
industrial gas turbine performance.
