Characteristics: It is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has moderate plasticity under annealing, fresh quenching and hot conditions. It has good spot welding weldability. The aluminum tube has a tendency to form intergranular cracks when using gas welding and argon arc welding; The machinability of the aluminum tube after quenching and cold work hardening is still good, but it is not good in the annealed state. The corrosion resistance is not high, and anodizing treatment and painting methods are often used or the surface is coated with aluminum layer to improve the corrosion resistance. It can also be used as a mold material.
Advantages of 5052 seamless aluminum tube

:
The first is the advantages of welding technology: the welding technology of thin-walled copper-aluminum pipes suitable for industrialized production is called a difficult problem, and it is the key technology of replacing copper with aluminum for connecting pipes of air conditioners.
The second is the service life advantage: from the perspective of the inner wall of the aluminum tube, because the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting tube will not corrode.
The third is the energy-saving advantage: 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-saving, or in other words, the better the heat insulation effect, the more energy-saving.
Fourth, it has excellent bending performance and is easy to install and move.
