Aluminum tube characteristics
For a kind of high-strength hard aluminum, it can be strengthened by heat treatment. It has moderate plasticity in annealing, just quenching, and hot state. It has good spot welding performance. When gas welding and argon-arc welding, aluminum tube has the tendency to form intercrystalline cracks; aluminum tube The machinability is still good after quenching and cold hardening, and is poor in the annealed state. The corrosion resistance is not high, and anodizing and painting methods are often used or aluminum layers are added on the surface to improve the corrosion resistance. It can also be used as a mold material.
Aluminum tube advantages:
First, the welding technology advantages: suitable for industrial production of thin-walled copper-aluminum pipe welding technology, known as the world-class problem, is the key technology of air-conditioning connection tube aluminum substitute copper.
Second, the service life advantage: From the perspective of the inner wall of the aluminum pipe, because the refrigerant does not contain moisture, the inner wall of the copper-aluminum connection pipe will not be corroded.
Third, energy-saving advantages: air-conditioning indoor unit and outdoor unit connection pipe, the lower the heat transfer efficiency, the more energy-efficient, or that the better the insulation effect, the more power.
Fourth, excellent bending performance, easy installation and transfer.
