    Abstract: An aluminum base alloy containing zinc, copper and magnesium together with manganese and with specially controlled composition limits exhibits very high strength when thermally treated to a condition having high resistance to stress corrosion cracking. Improved products of the alloy also exhibit low quench sensitivity and, accordingly, high strength even in very thick sections. A special aging treatment produces the optimum combination of strength and resistance to stress corrosion cracking properties. This invention relates to improved wrought products and to a method of their production.

    Abstract: ALUMINUM ALLOY PLATE CONTAINING 4.4 TO 10% MAGNESIUM AND STRAIN HARDENED TO IMPROVE ITS STRENGTH TO A LEVEL OF AT LEAST 40% GREATER THAN THE STRENGTH IN THE ANNEALED STATE IS IMPARTED WITH SUBSTANTIALLY FREEDOM FROM SUSCEPTIBILITY OF EXFOLIATION CORROSION. THE PROCESS INCLUDES ROLLING AT MINIMUM TEMPERATURES OF ABOUT 420* TO 650*F. DEPENDING ON THE AMOUNT OF MAGNESIUM PRESENT, TO PRODUCE THE STRAIN HARDENED PRODUCT AND COOLING AT SPECIALLY CONTROLLED RATES.
