6061 aluminium is one of the most versatile heat-treatable aluminium alloys, with good formability and high resistance to corrosion. Containing magnesium and silicon additions, alloy 6061 features medium strength relative to 2000 or 7000 series aluminium alloys. 6061 is one of the most common alloys of aluminium for general-purpose use, and is highly-weldable using MIG or TIG methods. The response to anodization of 6061 aluminium is among the highest in class.
Rolled Alloys stocks wrought 6061 aluminium in the T6511 condition. Extruded Bar is solution heat treated (960-1075°F) and quenched, then stretched a nominal 2% for stress relieving purposes before artificially aging (340-360°F). This combination of solution treatment, water quenching, and artificial aging imparts high strength.
