Use of aluminum alloys in automobiles 2

                    DRIVETRAIN & POWERTRAIN

                  The frame to support the drivetrain and powertrain requires both high rigidity and light weight. For this reason, frame
                  structures using high-strength structural aluminum alloy sheet and extruded shapes are increasingly being used.
                  More aluminum forged products are also being used for the suspension, as well as parts such as brake calipers, hub
                  carriers, and steering knuckles.

                                                                                           Hub carriers

                                                          fuel system, brakes, and sensors from
                                                          the high heat of the engine exhaust

                       As critical safety components, these
                       need to be highly reliable. The use of
                       high-strength forged aluminum parts is



                                                            Aluminum wheels
                                                           Although both cast and forged aluminum
                                                           wheels are used, forged aluminum
                                                           wheels are lighter and stronger.
