摘要
An aluminum-based alloy composition having improved corrosion resistance and high extrudability consists essentially of about 0.1-0.5% by weight of manganese, about 0.05-0.12% by weight of silicon, about 0.10- 0.20% by weight of titanium, about 0.15-0.25% by weight of iron and the balance aluminum, wherein the aluminum alloy is essentially copper free. The inventive alloy is useful in automotive applications, in particular, heat exchanger tubing and finstock, and foil packaging. The process provided by the invention uses a high extrusion ratio and produces a product having high corrosion resistance.
