[0002] Aluminum is a light, silvery-white metal with high ductility. Aluminum products are typically manufactured in rods, sheets, foil, powder, ribbon, and filament forms. In moist air, it forms an oxide film that protects the metal from corrosion. Aluminum is the most abundant metallic element in the Earth's crust, second only to oxygen and silicon. With the development of the three major industries of aviation, construction, and automobiles, aluminum production and application are increasing. Among aluminum products, aluminum tubes are the most widely used. These tubes are made from pure aluminum or aluminum alloys extruded into long, hollow metal tubes that extend longitudinally.

[0003] Aluminum tubes have low density but relatively high strength, which is close to that of high-quality steel. In addition, they have good plasticity and can be processed into various profiles. They have excellent electrical conductivity, thermal conductivity and corrosion resistance. Therefore, they are widely used in industry, and their usage is second only to steel.
