Features & Uses of Aluminum Tubes - diamontime - 06-07-2021 Aluminum is a common material in our lives. From building materials to food, we are all exposed to aluminum. Today we will talk about the advantages of aluminum tubes. 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 tubes have a tendency to form intergranular cracks when gas welding and argon arc welding are used; aluminum tubes The machinability is good after quenching and cold work hardening, 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 tube advantages: First, the welding technology advantage: the thin-walled copper-aluminum tube welding technology 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 for air conditioners. The second is the service life advantage: from the perspective of the inner wall of the aluminum tube, because 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 of the connecting pipeline between the indoor unit and the outdoor unit of the air conditioner, the more energy-saving, or in other words, the better the heat insulation effect, the more energy-saving. Fourth, it has excellent bending performance and is easy to install and move. Uses of aluminum tubes Aluminum tube is a kind of metal tube, which refers to a metal tube material that is extruded, cold drawn or forged with pure aluminum or aluminum alloy to be hollow along its full length in the longitudinal direction. There are one or more closed through holes with uniform wall thickness and cross-section, and they are delivered in a straight line or in rolls. Aluminum tube is divided into aluminum alloy straight tube and aluminum alloy coiled tube. Aluminum pipe has the advantages of corrosion resistance, light weight and low price. Aluminum tubes are divided into extruded aluminum tubes, cold drawn aluminum tubes, and forged aluminum tubes. Aluminum tubes are divided into small aluminum tubes, small diameter aluminum tubes, capillary aluminum tubes, large diameter aluminum tubes, and large aluminum tubes according to their outer diameters. Cold drawn and forged aluminum tubes are truly seamless aluminum tubes, and extruded aluminum tubes are invisible to the naked eye. They can also be called seamless aluminum tubes. Aluminum tubes are widely used in industries such as automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanics, homes, and construction. Supply aluminum tube specifications: outer diameter 1-1000 mm, wall thickness 0.1-100 mm, length 10 mm-9000 mm, Aluminum tube shape: round, square, rectangular, special-shaped tube, pattern tube Aluminum tube production process: extrusion, cold drawing, fine drawing, forging, Aluminum tube surface: aluminum natural color, oxidized, sprayed.
