Aluminium alloy 6060 is a medium-strength, heat-treatable alloy with slightly lower strength than 6005A. It offers excellent corrosion resistance, very good weldability, and good cold formability, especially in T4 temper. Alloy 6060 is commonly used for complex cross-section extrusions and responds very well to anodising.
Alloy 6060 is typically used for extrusions requiring complex shapes and/or anodising:
