The 2A11 Aluminum Tube is a high-strength aluminum alloy tube made from the 2A11 (LY11) aluminum grade — an Al-Cu-Mg high strength hard aluminum with good mechanical properties and weldability. It is widely used in precision industries, aerospace, military and structural applications that demand strength, toughness, and reliable performance.
2A11 Aluminum Tube
The 2A11 Aluminum Tube is a high-strength aluminum alloy tube made from the 2A11 (LY11) aluminum grade — an Al-Cu-Mg high strength hard aluminum with good mechanical properties and weldability. It is widely used in precision industries, aerospace, military and structural applications that demand strength, toughness, and reliable performance.
This alloy supports heat treatment to further improve strength, exhibits good spot welding and machinability after cold working, and can be finished with anodizing or painting to enhance corrosion resistance.
