AIRWARE(TM) Technology by Alcan on the Airbus A350 XWB

PARIS, July 20, 2010 - Alcan Global Aerospace Transportation and Industry (Alcan
Global ATI), part of Alcan Engineered Products - a business unit of Rio
Tinto, announces that it has signed a contract agreement with Airbus through
to 2020 to supply AIRWARE(TM), aluminum-based technology, for the A350 XWB.
Contract specific terms were not disclosed.

AIRWARE(TM) is a comprehensive offer of complementary Low
Density Alloys (aluminum-lithium), best suited to feature in all parts of the
aircraft primary structure.

In the framework of the contract, AIRWARE(TM) 2050 plate and
forging stock will be used in the manufacturing of critical parts of the
internal wing structure contributing to reach significant weight savings and
reducing the corrosion impact on aircraft parts. AIRWARE(TM) has also been
chosen to produce fuselage parts.

Manufactured both at Alcan Global Aerospace facilities in
Issoire, France and Ravenswood, USA, AIRWARE(TM) is the demonstration of the
company's commitment to supply the aerospace industry with the most
performing technologies enabling aircraft manufacturers to fulfil their
objectives in terms of fuel consumption, payload and range.

"One of our key drivers in developing AIRWARE(TM) was to bring
to market a comprehensive technological solution providing our customer with
an effective and innovative response to its main engineering challenges,"
said Christophe Villemin, Alcan Global Aerospace President.

Leveraging aluminum recyclability without property loss, Alcan
and Airbus have also engaged into a full recycling program committing to
reclaim a significant proportion of the aluminium chips (i.e. "swarf")
generated during manufacturing. This recycling solution is a clear value add
to the overall supply chain. It demonstrates both companies' commitment to
reducing environmental impact and makes AIRWARE(TM) a material of choice for
the aerospace industry.
