NEWLY DEVELOPED STRONG AND DUCTILE ALUMINIUM MATERIALS FOR VEHICLE BODIES

NEUERE ENTWICKLUNG GUT UMFORMBARER UND FESTER ALUMINIUMWERKSTOFFE FUER KAROSSERIETEILE

Of the many different aluminium alloys investigated, those of the Al Mg Si, Al Cu Mg and Al Mg groups have appeared to provide the optimum combination of strength and ductility. This article evaluates materials of these groups in the light of their chemical composition, strength, ductility, weldability, paint adhesion, corrosion resistance and recyclability. The various technical data are presented in tabular form. For the manufacture of highly deformed components, such as e.g. doors and wings, the ductility of the material is most important. Of particular utility in view of its ductility, measured in terms of isotropy, yield stress, stress-strain curves and practical experience, is Anticorodal 120. In relation to weldability the Al Mg alloys and in particular the Al Mg Si alloys possess advantages in being equally suitable for spot-welding or fusion welding. After suitable chemical treatment, such as treatment with phosphates or chromates, all the above alloys provide good paint adhesion. A further important argument for the use of aluminium is the greater durability and corrosion resistance in comparison with steel. The scrap value of aluminium body components is high in comparison with other vehicle materials except copper. (TRRL)
