Aluminum alloys are used in advanced applications because of their combination of high strength, low density. Due to excellent strength vs. density ratio, Al-Cu-Mg alloys are used in aerospace applications. The objective of this work is to improve the properties of Al-Cu-Mg alloys such as corrosion resistance in 3.5%NaCl solution by using quenching medium of 30% polyethylene glycol and addition alloying elements, such as Cd , Ag and Cd & Ag together to this alloy and to determine the effects of artificial ageing on the properties. An improvement of corrosion resistance in 3.5% NaCl solution when the alloys quenched in polymer solution have been higher corrosion resistance than these quenched in water and better of them corrosion resistance was in D alloy (containing 0.4 Cd and 0.3 Ag together) at aging temperature 150 ºC.
