Features and advantages of aluminum tubes




Aluminum tube 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 gas welding and argon arc welding are used; 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.


Aluminum tube advantages: First, welding technology advantages: the welding technology of thin-walled copper-aluminum tubes suitable for industrialized production is known as a world-class problem and is a key technology for replacing copper with aluminum for connecting pipes for 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 pipe between the indoor unit and the outdoor unit of the air conditioner, the more energy-saving.
Fourth, excellent bending performance, easy to install and move.
