Aluminum Alloy, Sheet and Plate, Alclad, 4.4Cu - 1.5Mg - 0.60Mn (Alclad 2024, -T81 Sheet, -T851 Plate), Solution Heat Treated, Cold Worked and Artificially Aged
This specification covers an aluminum alloy in the form of Alclad sheet and plate supplied in the –T81/-T851 temper. These products have been used typically for high strength parts requiring higher yield strength than is afforded by naturally aged tempers of this alloy and maximum corrosion resistance and whose fabrication does not involve welding, but usage is not limited to such applications.
AMS4478 is a new specification for Alclad 2024-T81/-T851 sheet and plate to facilitate stabilization of AMS-QQ-A-250/5.
