The aircraft industry requires improved aluminium alloy sheet material that enables higher performance while simultaneously delivering reduced costs. The property profile of AlMgSc alloys permits a beneficial application in terms of weight and costs for e.g. high lift components of Airbus aircrafts. Reduced density in the range of today’s Al-Lithium alloys, good fatigue and damage tolerance properties, excellent corrosion resistance, good weldability as well as an adequate static performance are the key properties of these alloys. The application of advanced manufacturing technologies such as Laser Beam and Friction Stir Welding in combination with a following creep forming process simplifies further integration of structural components and offers additional weight and cost reduction potential. This presentation will provide an overview of the overall process chain, comprising the design concepts, the production of AlMgSc sheet and the following manufacturing steps and will show the weight reduction potential of these alloys based on trade study results.
