Aluminum Tube Hollow Pipe 6061T6 Hard Alloy Round Tube 6063 Thick Thin Wall

Aluminum tube is a type of non-ferrous metal tube, referring to a hollow metal tubular material made from pure aluminum or aluminum alloy through extrusion processing along its entire longitudinal length.
Aluminum tubes are mainly divided into the following categories:
By shape: square tubes, round tubes, patterned tubes, special-shaped tubes, and global aluminum tubes.
By extrusion method: seamless aluminum tubes and ordinary extruded tubes.
By precision: ordinary aluminum tubes and precision aluminum tubes, with precision aluminum tubes generally requiring further processing after extrusion, such as cold drawing, precision drawing, and rolling.
By thickness: ordinary aluminum tubes and thin-walled aluminum tubes.
Properties: corrosion-resistant, lightweight.
Characteristics
As a high-strength hard aluminum, it can be strengthened by heat treatment. It has moderate plasticity in annealed, freshly quenched, and hot states, with good spot weldability. When using gas welding and argon arc welding, aluminum tubes tend to form intergranular cracks. The machinability of aluminum tubes is acceptable after quenching and cold working but poor in the annealed state. Corrosion resistance is not high, so anodizing, painting, or surface cladding with an aluminum layer is often used to improve corrosion resistance. It can also be used as a mold material.
Advantages of aluminum tubes: First, welding technology advantage: The thin-walled copper-aluminum tube welding technology suitable for industrial production is known as a super challenge and is a key technology for replacing copper with aluminum in air conditioner connecting tubes.
Second, service life advantage: From the perspective of the inner wall of the aluminum tube, since the refrigerant contains no moisture, the inner wall of the copper-aluminum connecting tube will not corrode.
Third, energy-saving advantage: For the connecting pipes between the indoor and outdoor units of air conditioners, the lower the heat transfer efficiency, the more energy-saving, or in other words, the better the insulation effect, the more electricity is saved.
Fourth, excellent bending performance, easy to install and relocate.
