This is a high quality hexagon Aluminum tube profile anodizing in blue red black color.
Aluminium tube is a kind of non-ferrous metal tube, which refers to a metal tubular material that is made of pure aluminum or aluminum alloy through extrusion processing to be hollow in the longitudinal direction. There can be one or more closed through holes, wall thickness, uniform cross-section, and delivery in a straight line or in a roll. It is widely used in industries such as automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical and household appliances. Aluminum tubes are everywhere in our lives.
Aluminum tubes are mainly divided into the following types :
According to the shape: square tube, round tube, pattern tube, special-shaped tube;
According to the extrusion method: seamless aluminum tube and ordinary extruded tube;
According to the precision: ordinary aluminum tubes and precision aluminum tubes, of which precision aluminum tubes generally need to be reprocessed after extrusion, such as cold drawing, fine drawing, and rolling.
According to thickness: ordinary aluminum tube and thin-walled aluminum tube.
Performance: corrosion resistance, light weight.
It is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has moderate plasticity under annealing, fresh quenching and hot conditions. It has good spot weldability. Aluminum pipes tend to form intergranular cracks when gas welding and argon arc welding are used; aluminum pipes The machinability is good after quenching and cold work hardening, but poor in the annealed state. The corrosion resistance is not high. Anodizing and power coating 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.
Advantages of aluminum tube: First, the advantages of welding technology: the welding technology of thin-walled copper-aluminum tubes suitable for industrialized production is called a problem, and it is the key technology of replacing copper with aluminum for connecting tubes of air conditioners.
The second is the service life advantage: 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.
The third is the energy-saving advantage: the lower the heat transfer efficiency, the more energy-saving the pipeline connecting the indoor unit and the outdoor unit of the air conditioner. In other words, the better the heat insulation effect, the more energy-saving.
Fourth, excellent bending performance, easy to install and move.
Hexagonal aluminum tube surface treatment chemical treatment:
Oxidation, electrophoresis coating, fluorocarbon spraying, powder spraying, wood grain transfer
Mechanical treatment: mechanical wire drawing, mechanical polishing, sandblasting.
