Aluminum tube is a kind of non-ferrous metal tube, refers to the use of pure aluminum or aluminum alloy extruded into a hollow metal tubular material along its longitudinal full length.
Aluminum tubes are mainly divided into the following types
According to the appearance of points: square tube, round tube, pattern tube, shaped tube, global aluminum tube.
According to the extrusion method: seamless aluminum tube and ordinary extruded tube
According to precision points: ordinary aluminum tubes and precision aluminum tubes, precision aluminum tubes in general need to be re-processed after extrusion, such as cold-drawn fine pumping, rolling.
According to thickness: ordinary aluminum tube and thin-walled aluminum tube
Performance: corrosion resistance, light weight.
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.
The second is the advantage of service life: From the perspective of the inner wall of the aluminum tube, since the refrigerant does not contain moisture, the corrosion of the inner wall of the copper-aluminum connection tube will not occur.
The third is the advantage of energy conservation: the connection between the indoor unit and the outdoor unit of the air conditioner. The lower the heat transfer efficiency, the more energy-efficient, or, the better the insulation effect, the more energy-efficient.
Fourth, excellent bending performance, easy installation and transfer.
