Corrosion resistant, drawable and bendable aluminum alloy, process of
making aluminum alloy article and article
Abstract:
An aluminum-based alloy composition having improved combinations of corrosion resistance, drawability, bendability and extrudability consists essentially of, in weight percent, not more than about 0.03% copper, between about 0.1 and up to about 1.5% manganese, between about 0.03 and about 0.35% titanium, an amount of magnesium up to about 1.0%, less than 0.01% nickel, between about 0.06 and about 1.0% zinc, an amount of zirconium up to about 0.3%, amounts of iron and silicon up to about 0.50%, up to 0.20% chromium, with the balance aluminum and inevitable impurities. A process of making an aluminum alloy article having high corrosion resistance, drawability, bendability and hot deformability is also provided.
