Alcan Global Aerospace Launches AIRWARE(TM), Tomorrow's Aircraft Technology

EUR42.5M Will be Invested in Issoire and Voreppe Sites (France)

PARIS, July 20, 2010 - Alcan Global Aerospace, Transportation and Industry (Alcan
Global ATI), a business unit of Alcan Engineered Products (Rio Tinto Group)
announces the launch of AIRWARE(TM), tomorrow's aircraft technology.
AIRWARE(TM) is a comprehensive offer of complementary and high-performance
Low Density Alloys, best suited to feature in all parts of the aircraft
primary structure. AIRWARE(TM) represents a unique solution to the current
challenges aircraft manufacturers are facing, allowing them to combine weight
reduction with lower assembly and maintenance costs, and reduction of the
overall environmental print.

Alcan Global ATI's goal is to make AIRWARE(TM) the solution of
choice for major future aerospace programs. EUR42.5 million will be therefore
invested in the production site at Issoire and the R&D center at Voreppe,
both located in France. While Issoire will be equipped with the very first
industrial casthouse in the world capable to produce advanced Low Density
Alloys (aluminum-lithium), the Voreppe R&D center's one will focus on
developing new applications.

"With AIRWARE(TM), we turn a new page in the aerospace
industry. By offering manufacturers a solution to lighten aircraft
structures, cut assembly and maintenance costs while benefiting from aluminum
infinite recyclability, we are demonstrating our commitment to innovate and
meet our customers' needs", said Christophe Villemin, Alcan Global ATI
President.

AIRWARE(TM)'s high technological content and value added make
it perfectly suited for optimizing aircraft production processes. The use of
Alcan advanced welding techniques combined with the introduction of recycling
systems boosts AIRWARE(TM)'s performance, thereby increasing the aerospace
industry's efficiency and reducing its overall environmental footprint.
AIRWARE(TM) is 100% recyclable, can deliver 20% weight reductions for
aircraft primary parts and guarantees longer heavy maintenance intervals, of
up to at least 12 years.

"Major aircraft manufacturers have already chosen AIRWARE(TM)
for their new program: Airbus for the A350-XWB and Bombardier for the
CSeries. We are particularly proud to look into the future of the aerospace
industry by offering the reliability and performance of our solutions",
concluded Christophe Villemin.
