Tensile Strength (> 440 MPa) and Elongation  ≥10(%)


 
The characteristics of Aluminium Alloy Tube 2014
Comparing with 2A50, Aluminium Alloy Tube 2014 belongs to hard aluminium alloy and forged aluminium alloy. Compared with 2A50, it has higher strength and better thermal strength, but its plasticity is not as good as 2A50 in hot state. Aluminium Alloy Tube 2014 has good machinability, good contact welding, spot welding and roll welding performance, poor arc welding and gas welding performance, and can be strengthened by heat treatment with extrusion effect.
