The aluminum tube is a kind of high-strength duralumin, which can be strengthened by heat treatment. It has medium plasticity in annealing, hard quenching and hot state, and good spot welding. When gas welding and argon arc welding are used, the aluminum tube tends to form intergranular cracks; The machinability of aluminum tube is good after quenching and cold work hardening, but it is not good in the annealing state. The corrosion resistance is not high. Anodic oxidation and painting methods are often used or aluminum coating is added on the surface to improve the corrosion resistance. It can also be used as die material.

Mechanical Behavior

Main Advantage

First, the advantages of welding technology: the welding technology of thin-walled copper aluminum tubes, which is suitable for industrial production, is known as a world-class problem, and is the key technology of replacing copper with aluminum for connecting tubes of air conditioners.

Second, the advantage of service life: from the perspective of the inner wall of the aluminum tube, since the refrigerant does not contain water, the inner wall of the copper aluminum connecting tube will not be corroded.

Third, energy saving advantages: the lower the heat transfer efficiency of the connecting pipeline between the indoor unit and the outdoor unit of the air conditioner, the more energy will be saved, or the better the insulation effect, the more power will be saved.

Fourth, excellent bending performance, easy to install and move.
