The automotive industry is interested to reduce vehicles weight, because of the need to reduce the fleet fuel consumption. Within this scenario, high strength aluminum alloys are a viable alternative to heavier steel currently adopted. In particular 7xxx series aluminum alloys, due to their excellent strength to weight ratio, are drawing the attention of carmakers. The development of a proper precipitation hardening process is extremely important in order to obtain the best results in terms of strength and it is what has been done in this work for the alloy 7046. This thesis evaluates the microhardness and tensile testing results. The latter were performed at room temperature, at warm forming temperature and after the alloy was heated up to different temperatures for 5 minutes, at the end of different artificial ageing treatments.
