Use of aluminum alloys in automobiles   1

                     BODY & CHASSIS

                  Global fuel efficiency standards are getting stricter and stricter. Fuel economy regulations
                  intended to reduce energy consumption and CO2 emissions are being tightened not only
                  in Japan, the U.S.A. and Europe, but also in emerging countries. Reduction of vehicle
                  weight is a key element of CO2 emission regulations. The adoption of aluminum alloys for
                  automobiles, that began with cast-metal components such as engine parts, is now
                  progressing to full-scale adoption thanks to the improved strength and formability of
                  wrought aluminum alloys.

                            important structural member that
                            supports the top of the suspension arm.
