2219 2A11 2A14 2A50 aluminum tube pipe

2219 aluminum tube pipe has poor corrosion resistance, good machinability, poor solderability, easy arc welding and spot welding. It is suitable for structural parts and high strength welds working at high temperature of 315 degrees Celsius.





2A11 aluminum tube pipe has medium strength, good plasticity under annealing, rigid quenching and heat condition. It can be enhanced by heat treatment. It is used in the state of quenching and natural aging. The weldability of spot welding is good. There is crack tendency in gas welding and argon arc welding; it is good in the state of quenching and aging, and is bad in the state of annealing.

2A14  aluminum tube pipe main chemical components are zinc, iron, magnesium and aluminum. It has good machinability, resistivity, spot welding and seam welding.
