Material Notes:
Features good weldability, excellent damage tolerance, good corrosion resistance, creep-formability. Aleris AlMgSc alloy AA5024 H116 allows simplification of the manufacturing process of aircraft fuselage components. With AA5024 H116 AlMgSc, stringer reinforced aircraft fuselage components can be either Laser Beam Welded (LBW) or Friction Stir Welded (FSW) when the individual parts are still flat, without any prior treatment. The single or double curvature of the fuselage part required for the aircraft body is achieved by creep forming at elevated temperature.Recommended for use as fuselage skin sheet with medium strength but excellent damage tolerance and corrosion properties and can potentially replace traditionally used 2xxx alloys even as drop-in solution.Temper, AMS and MMPDS registration pending. AA5024 H116 is covered by the Airbus specification AIMS 03-04-055 Information and property data for creep formed and welded (if applicable) sheet provided by Aleris.
