The project deals with AlZnMgCu alloys. They show a strong reaction to age-hardening and the highest strength of all conventional aluminium wrought alloys. The alloys are mainly used in the aviation and aerospace industry because of their favourable combination of high strength and low density. The strength potential of 7xxx-wrought alloys is comparable to that of medium- to high-strength structural steels. For a high content of alloying elements, the balance between composition and heat treatment is investigated to find increased mechanical properties.
