Abstract
An aluminum alloy of age-hardening type indispensably containing copper, magnesium and silicon, being optionally added thereto traces of any one or more than one element selected from vanadium, manganese, chromium, zirconium and titanium. A sheet or strip made from said alloy ingot, being submitted to solution treatment followed by precipitation process can improve forming properties, such as tensile strength, LDR and/or earing ratio, and be free from stretcher-strain marks. Said sheet or strip maintains high strength particularly when it is submitted to baking i.e. high temperature curing of paint coated thereon.
