tube can be strengthened by heat treatment. It is a kind of high-strength hard aluminum. It has moderate plasticity under annealing, fresh quenching and hot conditions. It has good spot welding performance. The aluminum tube has a tendency to form intergranular cracks when using gas welding and argon arc welding; 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 profile manufacturers introduce the four major characteristics of aluminum products: 1, energy-saving advantages. The connecting pipeline between the indoor unit and the outdoor unit of the air conditioner, the lower the heat transfer efficiency, the more energy-saving, or in other words, the better the heat insulation effect, the more energy-saving. 2, service life. From the perspective of the inner wall of the aluminum tube, since the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting tube will not corrode. 3. Welding technology. The welding technology of thin-walled copper-aluminum pipes suitable for industrialized production is known as a world-class problem, and it is the key technology for replacing copper with aluminum for connecting pipes of air conditioners. 4. Excellent bending performance, easy to install and move the machine.
