    (翻译)Cars and other motor vehicle are constructed from a complex mix of raw materials. Steel(iron together with small amounts of additional minerals) forms the bulk of the motorcar-its primary use is in the body shell, the wheel,the drivertrain and parts of the engine. Other metals are also important,but to differing degrees.

    Aluminium is used by a number of manufacturers for the body shell and for many engine components. Iron and zinc are also used for various components (including the exhaust system and engine blocks).Precious metals are becoming more important with the widespread use of catalytic converters.Copper and lead are also used(copper in wiring, lead in betteries)

    The motor industry is therefore a major customer for metal producers, and the pproportion of metal consumption used in tuansport by the main developed countries is:

    Iron and steel 30% Lead 46%

    Aluminium 23% Platinum 41%(exhaust fume control)
