Features

This is a high-strength aluminum alloy, capable of heat treatment strengthening. It has moderate plasticity in annealed, quenched, and hot conditions, good spot welding properties, but 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 when in the annealed state. Its corrosion resistance is not high, so it is commonly treated with anodizing and painting or coated with an aluminum layer on the surface to enhance its corrosion resistance. It can also be used as a mold material.

Advantages of Aluminum Tubes:

Firstly, welding technology advantage: 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: Due to the refrigerant being free of moisture, the inner wall of the copper-aluminum joint pipe will not corrode.

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 electricity-saving.
