Product Description

aluminum tube fabrication

Aluminum tube is a kind of non-ferrous metal tube, which is made of pure aluminum or aluminum alloy extruded and processed into a hollow metal tube material along its longitudinal length.

It can have one or more closed through-holes, uniform wall thickness and cross-section, and delivered in a straight line or in a roll. Widely used in automobile, ship, aerospace, aviation, electrical appliances, agriculture, electromechanical, household and other industries.


Aluminum tubes are mainly divided into the following categories

  • According to the shape:square tube, round tube, pattern tube, shaped tube, global aluminum tube.
  • According to the extrusion method: seamless aluminum tube and common extrusion tube
  • According to the precision: ordinary aluminum tube and precision aluminum tube, which precision aluminum tube generally need to be reprocessed after extrusion, such as cold-drawn precision extraction, rolling.
  • According to the thickness: ordinary aluminum tube and thin-walled aluminum tube

Performance: corrosion resistance, light weight.


A kind of high strength hard aluminum, can be heat treated and strengthened, in annealed, just quenched and hot state plasticity is medium, spot welding weldability is good, with gas welding and argon arc welding aluminum tube has the tendency to form intergranular cracks; aluminum tube in quenching and cold hardening machinability is still good, in the annealed state is bad. Corrosion resistance is not high, often using anodic oxidation treatment and painting methods or surface cladding aluminum layer to improve corrosion resistance. It can also be used as mold material.

Aluminum tube advantages

  1. First, welding technology advantages: suitable for industrial production of thin-walled copper and aluminum tube welding technology, known as a world-class problem, is the key technology of the air conditioner connection tube aluminum instead of copper.
  2. Second is the service life advantage: from the aluminum tube wall, because the refrigerant does not contain moisture, copper and aluminum connection tube wall will not occur corrosion phenomenon.
  3. Third, the energy-saving advantage: air conditioner indoor unit and outdoor unit connection pipeline, the lower the heat transfer efficiency, the more energy efficient, or, the better insulation effect, the more power saving.
  4. Fourth, the excellent bending performance, easy to install and move the machine

Surface treatment:

Chemical treatment: oxidation, electrophoretic coating, fluorocarbon coating, powder coating, wood grain transfer

Mechanical treatment method: mechanical drawing, mechanical polishing, sandblasting


Aluminum tubes are widely used in all walks of life, such as: automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanics, home furnishings, etc. Aluminum tubes have become ubiquitous in our lives.
