Advantages and application of aluminum tubes

- Sep 16, 2018-

The aluminum 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 welding property. The aluminum tube has a tendency to form intergranular cracks when using gas welding and argon arc welding; The aluminum tube has good machinability after quenching and cold 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.

Advantages of aluminum tube: 

First, the advantage of welding technology: The thin-wall copper-aluminum tube welding technology suitable for industrial production is called the problem, and it is the key technology of the aluminum-based copper of the air-conditioner connecting tube.

Second, the service life advantage: from the inner wall of the aluminum tube, since the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting tube does not corrode.

The third is the energy-saving advantage: the connecting 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.

Fourth, the bending performance is excellent, easy to install and move!
