Experiments were made, through tensile, electric conductivity and corrosion tests, to examine the effects of cold-working on the aging characteristics in 2024, 7075 and 6061 aluminium alloys, which are for aircraft skin materials.
Findings are as follows: The effect of cold-working is remarkably different according to the chemical composition of alloys; it is notable in 2024 alloy but little in 7075 and 6061. For 2024 alloy, the starting time of artificial aging after solution treatment and cold-working is very important. It should be started after completion of natural aging to get maximum strength. On the other hand, 6061 and 7075 alloys have split aging effect when cold-worked.
