Excellent bending performance, easy to install and move.
The anodizing of aluminum tubes is generally carried out in an acidic electrolyte, with aluminum as the anode. During electrolysis, the anion of oxygen interacts with aluminum to produce an oxide film. When the film is initially formed, it is not fine enough, and although it has a certain resistance, the negative oxygen ions in the electrolyte can still reach the surface of aluminum and continue to form an oxide film. With the increase of film thickness, the resistance also increases, thus the electrolytic current decreases. At this time, the outer oxide film in contact with the electrolyte is chemically dissolved. When the rate of oxide formation on the surface of aluminum is gradually balanced with the rate of chemical dissolution, the oxide film can reach the thickness under this electrolytic parameter. The outer layer of the anodic oxidation film of aluminum is porous, which is easy to absorb dyes and colored substances, so it can be dyed and improve its decoration. The corrosion resistance and wear resistance of the oxide film can be further improved after it is closed with hot water, high temperature steam or nickel salt.
peculiarity
It is a kind of high strength duralumin, which can be strengthened by heat treatment, has medium plasticity under annealing, hardening and hot state, and has good spot welding weldability. Aluminum tubes have a tendency to form intergranular cracks during gas welding and argon arc welding. The machinability of aluminum tube is good after quenching and cold hardening, but poor in annealing state. Corrosion resistance is not high, often using anodic oxidation treatment and painting method or surface coated with aluminum layer to improve the corrosion resistance. Can also be used as a mold material.

Due to the soft texture of aluminum, good ductility, with a silver-white luster, if the rolled sheet, with sodium silicate and other substances mounted on offset paper to make aluminum foil sheets, can also be printed. However, the aluminum foil itself is easy to oxidize and dark, friction, touch, etc., will fade, so it is not suitable for long-term preservation of book covers and other hot printing.
Aluminum foil can be divided into thick foil, single zero foil and double zero foil according to thickness difference. ① Thick foil: the thickness of 0.1 ~ 0.2mm foil. ② Single zero foil: the thickness of 0.01mm and less than 0.1mm/foil. ③ Double zero foil: The so-called double zero foil is the foil with two zeros after the decimal point when its thickness is measured in mm, usually the aluminum foil with a thickness of less than 0.0075mm.
Aluminum foil according to the surface state can be divided into one side of light aluminum foil and two sides of light aluminum foil. ① One side of light aluminum foil: double rolled aluminum foil, one side of the roll is bright, the surface is black, such aluminum foil is called a light aluminum foil. The thickness of one surface aluminum foil usually does not exceed.025mm. (2) Two-sided glazed aluminum foil: single rolled aluminum foil, two pictures and roll contact, the two sides of aluminum foil due to different surface roughness of the roll is divided into mirror two-sided glazed aluminum foil and ordinary two-sided glazed aluminum foil. The thickness of the two sides of light aluminum foil is generally not less than 0.01mm.

Aluminum alloy products
Aluminum alloy is the most widely used non-ferrous structural materials in the industry, and has been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural parts is increasing, which makes the weldability research of aluminum alloy further. The wide application of aluminum alloy has promoted the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of aluminum alloy, so the welding technology of aluminum alloy is becoming one of the hot spots of research. The density of pure aluminum is small (ρ=2.7g/cm3), about 1/3 of iron, low melting point (660℃), aluminum is face-centered cubic structure, so it has a high plasticity (δ:32~40%, ψ:70~90%), easy processing, can be made into a variety of profiles, plates. Good corrosion resistance; However, the strength of pure aluminum is very low, and the annealing state σb value is about 8kgf/mm2, so it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually add alloying elements and use heat treatment and other methods to strengthen aluminum, which gets a series of aluminum alloys. The alloy formed by adding certain elements can maintain the advantages of pure aluminum while maintaining high strength, σb values can reach 24 ~ 60kgf/mm2. This makes its "specific strength" (strength and specific gravity ratio σb/ρ) than many alloy steel, become an ideal structural material, widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry, aircraft fuselage, skin, compressor and other often made of aluminum alloy to reduce weight. The welding of aluminum alloy instead of steel plate can reduce the weight of the structure by more than 50%.
