Abstract
Aluminum alloy products are described which combine both good strength and resistance to pitting corrosion. They are extruded from an aluminum alloy of the AA1000, AA3000 or AA8000 series containing about 0.001 to 0.3% zinc and about 0.001 to 0.03% titanium. The alloy may also contain 0.001 to 0.5% manganese and about 0.03 to 0.4% silicon. These products are particularly useful in the production of extruded products, such as heat exchanger tubing.
