Abstract
An aluminum-based alloy composition having improved corrosion resistance and extrudability consists essentially of, in weight percent, an amount of copper up to about 0.03%, between about 0.1 and 0.5% manganese, between about 0.03 and 0.30% titanium, between about 0.06 and 1.0% zinc, an amount of iron up to about 0.50%, between about 0.05 and 0.12% Si, less than 0.01% manganese, less than 0.01% nickel, up to 0.5% chromium with the balance aluminum and incidental impurities. A process of making an aluminum alloy article having high corrosion resistance also is provided.
