What is aluminum tube?
Non-ferrous metal pipe
Aluminum pipe is a kind of non-ferrous metal pipe, refers to pure aluminum or aluminum alloy by extrusion processing along its longitudinal length hollow metal tube material.
Classification of aluminum tubes
Aluminum tubes are mainly divided into the following types
According to the shape: square pipe, round pipe, decorative pipe, special pipe, global aluminum pipe.
According to extrusion: seamless aluminum pipe and ordinary extrusion pipe
According to the precision: ordinary aluminum tube and precision aluminum tube, precision aluminum tube generally need to be reprocessed after extrusion, such as cold drawing fine pumping, rolling.
According to the thickness: ordinary aluminum tube and thin wall aluminum tube
Performance: corrosion resistance, light weight.
Features
It is a kind of high strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity under annealing, rigid quenching and heat state, and good spot welding weldability. It has the tendency to form intercrystalline cracks when using gas welding and argon arc welding. The machinability of aluminum tube is good after quenching and cold hardening, but bad in annealing state. Corrosion resistance is not high, often use anodic oxidation treatment and coating method or surface coated aluminum layer to improve corrosion resistance. It can also be used as mold material.
Advantages of aluminum tube: First, advantages of welding technology: thin-wall copper and aluminum tube welding technology suitable for industrial production, known as a world-class problem, is the key technology of aluminum instead of copper for air conditioner connecting tube.
Second, 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 and aluminum connection tube will not occur corrosion phenomenon.
Third, energy saving advantages: the connection pipeline between the indoor unit and the outdoor unit of the air conditioner, the lower the heat transfer efficiency, the more energy saving, or the better the insulation effect, the more electricity saving.
Four is good bending performance, easy to install, move machine.
What are the grades of aluminum tubes? Let's get to know:
1. 1060 aluminum tube: widely used, suitable for manufacturing chemical containers, compressed paste, shampoo bottles, hardcover perfume bottles, auto parts, etc.
2. 1070 aluminum tube: mainly used in the manufacture of food packaging, cooking utensils, building materials, printing, etc.
3. 3003 aluminum tube: with excellent anti-corrosion performance, suitable for manufacturing welding components, heat exchangers, air fluid fins, boiler mufflers, etc.
4. 5052 aluminum tube: with good corrosion resistance and processability, it is widely used in the manufacture of skylights, body panels, baffles, various wheel parts, building plates, containers, etc.
5. 6061 aluminum tube: one of the most widely used aluminum alloy models, with excellent mechanical properties and machinability, suitable for manufacturing aerospace parts, bicycle frames, auto parts, ships, etc.
6. 6063 aluminum tube: it is an alloy with high plasticity and good corrosion resistance, and has good weldability and forming processability. Because of its excellent corrosion resistance and moderate strength, 6063 aluminum pipe is widely used in construction, shipbuilding and chemical industry. In addition, 6063 aluminum tubes can be treated with anti-corrosion coatings to further improve their corrosion resistance.
7. LY12 aluminum tube: it is a kind of high strength and high hardness aluminum alloy, with good fatigue resistance and corrosion resistance. Due to its high strength and hardness, LY12 aluminum pipes are widely used in high load and wear resistant situations. For instance, in sectors such as aerospace, petrochemicals, and automotive manufacturing, LY12 aluminum tubes are used to manufacture parts that withstand high loads.
At present: aluminum tube is widely used in all walks of life, such as: automobile, ship, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, home, aluminum tube in our life has been everywhere.
