Weight reduction is the present and future issue in the automotive industry. The use of aluminum for bodywork is a growing solution due to the specific properties and the recyclability it offers. The unibody design concept with high productivity is developed for steel sheet metal car bodies. They can also be made with aluminum sheets with different product shapes (sheets, extrusions, castings etc.). The aluminum offers a wide variety of design options. The most important difference between aluminum and steel models is the predominant joining technique. In order to obtain optimal solutions from a technical and economical point of view, it is necessary to apply aluminum design concepts and correspondingly adapted manufacturing technologies.
