Features

For a high-strength hard aluminum, capable of heat treatment strengthening, it has moderate plasticity in annealed, quenched, and hot conditions, good spot welding weldability; however, there is a tendency to form intergranular cracks during gas welding and TIG welding. The aluminum tube maintains good machinability after quenching and cold working hardening, but is poor in the annealed state. Corrosion resistance is not high, and anodizing, painting, or adding 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 for 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: Looking at the inner wall of the aluminum tube, as the refrigerant contains no moisture, there will be no corrosion on the inner wall of the copper-aluminum joint pipe.

The third advantage: Energy-saving: The connection pipes between the indoor and outdoor units of the air conditioner, the lower the heat transfer efficiency, the more energy-saving, or in other words, the better the insulation effect, the more power-saving.
