Aluminum tubes are mainly divided into the following types:

According to the shape: square tube, round tube, pattern tube, special-shaped tube, global aluminum tube.

According to the extrusion way: seamless aluminum tube and ordinary extrusion tube

According to the precision: ordinary aluminum tube and precision aluminum tube, precision aluminum tube generally need to be reprocessed after extrusion, such as cold drawing, drawing, rolling.

According to the thickness: ordinary aluminum tube and thin wall aluminum tube

Performance: Corrosion resistance, light weight.

Features：

It is a kind of high strength duralumin, which can be strengthened by heat treatment, moderate plasticity in annealing, hardening and hot state, good spot welding welding, gas welding and argon arc welding aluminum tube has the tendency to form intercrystalline cracks; The machinability of aluminum tube is good after quenching and cold work hardening, but poor when annealed. The corrosion resistance is not high. Anodic oxidation treatment and coating method or aluminum coating is often used to improve the corrosion resistance. It can also be used as a mold material.

Aluminum pipe advantages: one is the advantage of welding technology: suitable for industrial production of thin-wall copper aluminum pipe welding technology, known as a world-class problem, is the key technology of air conditioner connecting pipe aluminum instead of copper.

Second, the service life advantage: from the perspective of the inner wall of the aluminum tube, because the refrigerant does not contain water, the copper and aluminum connecting tube inner wall will not corrosion phenomenon.

Three is the advantage of energy saving: the connection pipe 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 insulation effect, the more electricity saving.

Four is excellent bending performance, easy to install, move machine

Surface treatment：

Chemical treatment: oxidation, electrophoresis coating, fluorine carbon spraying, powder spraying, wood grain transfer printing

Mechanical treatment: mechanical drawing, mechanical polishing, sand blasting
