The aircraft industry requires improved aluminium alloy sheet and plate that enables higher performance while simultaneously delivering reduced costs. The high pressures on the Aircraft Original Equipment Manufacturers by the airline customers led to the development of new high performance aluminium alloys to be competitive against other materials such as fiber reinforced composites or other advanced metals.
This presentation will provide an overview of new alloys developed by Aleris for fuselage, wing structures and for use in general or integrated structures. The focus is placed on alloy 7081 which offers a superior strength-toughness balance compared to already existing 7xxx alloys such as e.g. 7050. Alloy 7081 is available in a wide thickness range in various tempers such as T7451 and T7651.
