Third-generation aluminum alloys 1441, 1424 and V-1461, V-1469 of medium and high strength, respectively, which have been developed as an alternative to the base aluminum alloys 1163 and V95 widely used in the aircraft industry, are studied. The advantages of the suggested alloys with respect to the strength, life characteristics, weldability and corrosion resistance are shown.
