In the aerospace community big concern is devoted to the development of new materials with high mechanical characteristics and low density. Many years ago composite materials were a big promise for aerospace applications but even today are still far from replacing aluminium alloys. In this work it will be studied the behaviour of fatigue-corrosion of six aluminium alloys. Most of these alloys are often used in aerospace structural components. One of the tested alloys, specifically the 6082,has been developed for offshore applications such as masts and structures used in sailing competitions. Crack growth rate versus stress intensification factors have been determined at different excitation frequencies and at different environmental conditions for all the six alloys considered.
