Features

This is a high-strength hard aluminum alloy that can be heat-treated for strengthening. It has moderate ductility in annealed, quenched, and hot conditions, good spot-welding properties, but a tendency to form intercrystalline cracks when gas-welded or TIG-welded. The aluminum tube maintains good machinability after quenching and cold working hardening, but is poor in the annealed state. Corrosion resistance is not high, so anodizing and painting methods or applying an aluminum cladding to the surface are commonly used to enhance corrosion resistance. It can also be used as a mold material.

Advantages of Aluminum Tubes:

Firstly, the advantage of welding technology: suitable for thin-walled copper and aluminum tube welding technology in industrial production, known as a challenge, and is the key technology for replacing copper with aluminum in air conditioner connecting pipes.

Secondly, the lifespan advantage: From the inside wall of the aluminum tube, since the refrigerant does not contain water, there will be no corrosion on the inside wall of the copper-aluminum connecting tube.

The third advantage is energy-saving: The connection pipes between the indoor and outdoor units of the air conditioner, the lower the heat transfer efficiency, the more energy-efficient; in other words, the better the insulation effect, the more electricity saved.
