According to the composition,
2014A T6 aluminum tube belongs to both hard aluminum alloy tube and forging aluminum alloy. Compared with 2A50, it has higher strength and better thermal strength due to its higher copper content, but its plasticity is not as good as 2A50 in the hot state. The alloy has good machinability, good contact welding, spot welding and rolling welding performance, and poor arc welding and gas welding performance.Heat treatment can be strengthened, there is extrusion effect;Corrosion resistance is not high, when the artificial aging inspection corrosion tendency.

2014A T6 aluminum tube is mainly used for applications requiring high strength and hardness (including high temperature).Heavy forgings, slabs and extruded materials are used in aircraft structural parts, multistage rocket first stage fuel tanks and spacecraft parts, wheels, truck frames and suspension system parts.
