Alcan Engineered Products Introduces Future-Ready Innovations at "Aluminium 2010" in Germany

ESSEN, Germany, September 15, 2010 - Alcan Engineered Products - a business unit of Rio Tinto -
showcases a unique range of innovative aluminium-based products offering
custom ready solutions to key industry sectors such as aerospace, automotive,
transportation, packaging, renewable energy at the ALUMINIUM 2010.

"We are proud to showcase these innovations on such a visible
scale", said Christel Bories, President and Chief Executive Officer of Alcan
EP. "It demonstrates how our strategy, which combines our unique R&D
capabilities with our innovation initiatives, as well as leveraging our close
relationships with major industry players, allows us to deliver future-ready,
cost effective and cutting-edge products for our customers."

Alcan EP showcases products for a wide range of applications. Among these
are:

    - Solar Surface(R) Selfclean: Alcan EP has developed an innovative
    functionality for solar mirrors with two protective coatings that
    give mirror surfaces a "selfcleaning" effect. This leading-edge
    technology ensures that solar mirrors always remain clean and efficient
    by preventing the build-up of dirt and other corrosive materials.

    - AIRWARE(TM) Tomorrow's Aircraft Technology: A comprehensive offer of
    complementary and high-performance Low Density Alloys, which are
    strongly suited to feature in all parts of the aircraft primary
    structure. AIRWARE(TM) technology's high technological content makes it
    perfectly suited for optimizing aircraft production processes.

    - New high-tech aluminium profiles for hybrid engines. The
    aluminium profile is being produced within extremely tight tolerances
    in the micro-meter range and integrated into the stator section of the
    electric engine. Hybrid cars can be operated by using only an electric
    transmission and operate nearly completely emission free. This
    engineering solution will contribute by increasing customer demand for
    low-emission hybrid cars.

    - Alcan Extrusions and Automotive Structures, part of Alcan
    EP, announced to supply 100km of aluminium power rail for a metro project
    in the Indian metropolis Bangalore. In addition to the production of the
    aluminium power rail system, Alcan will provide an engineering and
    service package through the Railtech-Alu-Singen Joint-Venture.

Alcan EP also announced that it has strengthened its
innovation programme based on a multiyear cooperation agreement with Swiss
Federal Institute of Technology. In this context Francesco Stellacci, tenured
associate professor at the Massachusetts Institute of Technology, was
appointed full professor at the Institute of Materials Science. The objective
of the cooperation between Alcan EP and EPFL is to accelerate the technical,
commercial development of lightweight materials for applications in major
industry sectors.
