As a kind of high strength aluminum tubes, can be strengthened by heat treatment, annealing, quenching and heat under the condition of rigid plasticity, good welding, gas welding and argon arc welding in aluminum has the tendency of intergranular crack formation; aluminum hardening in quenching and cold after the cutting performance is good, bad in annealing state. The corrosion resistance is not high, in order to improve the corrosion resistance of anodic oxidation treatment and often used methods of paint or aluminum surface layer. It can also be used as mould material.
Advantages of aluminum tube:
1.Welding technology advantages: suitable for industrial production of thin-walled copper aluminum tube welding technology, known as a world-class problem, is the key to the air conditioner connecting tube aluminum copper.
2.The service life advantage: from the inner wall of the aluminum tube, because the refrigerant does not contain moisture, copper and aluminum connecting pipe inner wall will not occur corrosion phenomenon.
3.Energy saving advantages: the connection between air conditioner indoor unit and outdoor unit, the lower the heat transfer efficiency, the more energy saving, or the better insulation effect, the more power saving.
4.The bending performance is good, easy to install and remove.
