In the past decade the demand for lighter structures and advanced manufacturing technologies has accelerated the development of AlMgSc alloys. With a density in the range of today’s Al-Lithium alloys, their excellent fatigue and damage tolerance properties, good corrosion resistance and very good weldability AlMgSc alloys offer huge benefits in terms of weight and cost savings. Currently AlMgSc alloys are being considered by Airbus for use in future fuselage shells and high lift components. The application of advanced manufacturing technologies such as Laser Beam and Friction Stir welding in combination with a subsequent creep forming process simplifies further integration of structural components and offers additional weight and cost reduction potential. This paper covers the overall process chain including the fabrication of AlMgSc products, the following manufacturing steps and an outlook on new developments by Aleris on AlMgSc type alloys.
