Characteristic：
For a high -intensity hard aluminum, heat treatment can be enhanced, and the plasticity is medium in annealing, just quenching and thermal state, and the welding is good. When the gas and the arc are welded, the aluminum tube has a tendency to form a crystal crack; the aluminum pipe is After quenching and cold, the cutting performance can be cut well, and it is poor when annealing. The corrosion resistance is not high, and the anode oxidation treatment and paint method or the surface of the surface are often used to improve the corrosion resistance. It can also be used as mold materials.
Advantages of aluminum tube:
The first is the advantages of welding technology: the thin -walled copper aluminum tube welding technology suitable for industrialized production is called a world -class problem. It is a key technology for air -conditioners to connect the aluminum copper.
The second is the advantages of service life: From the perspective of the inner wall of the aluminum tube, because the refrigerant does not contain moisture, the inner wall of the copper aluminum connecting tube will not cause corrosion.
Third, the advantage of energy saving: The connected pipeline of the indoor machine and the outdoor unit of the air conditioner, the lower the heat transfer efficiency, the more energy saving, or the better the thermal insulation effect, the better the electricity saving.
Fourth, bending performance is excellent, easy to install and move.
Surface treatment
Chemical treatment: oxidation, electrophoretic coating, floss spray, powder spraying, wood grain transfer
Mechanical treatment method: mechanical brushes, mechanical polishing, sand spray
Aluminum pipes are widely used in all walks of life, such as cars, ships, aerospace, aerospace, electrical appliances, agriculture, electromechanical, home furnishings, etc.
