The utility model is a high-strength duralumin, which can be strengthened by heat treatment and has medium plasticity in annealing, hardening and hot state. It has good weldability in spot welding and has a tendency to form intergranular cracks in aluminum tubes when using gas welding and argon arc welding. The machinability of aluminum tube is good after quenching and cold hardening, but bad when annealed. Corrosion resistance is not high, often using anodic oxidation treatment and paint method or surface coated with aluminum layer to improve the corrosion resistance. It can also be used as a mold material.
Advantages of aluminum tube: one is welding technology advantages: suitable for industrial production of thin-wall copper aluminum tube 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 inner wall of the aluminum tube, because the refrigerant does not contain moisture, the inner wall of the copper aluminum connection tube will not corrode.
Three is energy-saving advantage: air conditioner indoor unit and outdoor unit connection pipeline, the lower the heat transfer efficiency, the more energy saving, or, the better the heat insulation effect, the more power saving.
Four is excellent bending performance, easy to install, move
