The aluminum alloy tube is a kind of high-strength hard aluminum, which can be heat-treated and strengthened. It has moderate plasticity in annealing, quenching and hot state, and has good spot weldability. The aluminum tube has a tendency to form intergranular cracks during gas welding and argon arc welding. The aluminum tube has good cutting performance after quenching and cold work hardening, and is poor in the annealed state. The corrosion resistance is not high, and the anodizing treatment and painting method or the surface is coated with an aluminum layer to improve the corrosion resistance. It can also be used as a mold material.
Aluminum tube advantages:
(1) Advantages of welding technology: The thin-wall copper-aluminum tube welding technology suitable for industrial production is called a world-class problem, and it is the key technology for the aluminum-based copper of the air-conditioner connecting tube.
(2) Service life advantage: From the inner wall of the aluminum pipe, since the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting pipe does not corrode.
(3) Energy-saving advantages: the connection line between the indoor unit and the outdoor unit of the air conditioner, the lower the heat transfer efficiency, the more energy-saving, or the better the heat insulation effect, the more power-saving.
(4) Excellent bending performance, easy to install and transfer.
