2011 aluminum tube is a high-performance alloy tubing known for its excellent machinability and good mechanical strength, especially in precision machining applications. It contains copper with trace amounts of lead and bismuth, which improves cutting characteristics compared to many other aluminium grades. However, it typically has limited corrosion resistance and is less weldable than some other alloys.
