Aluminum alloy sheets can be divided into deformed aluminum alloys and cast aluminum alloys according to the processing method.
The so-called "raw aluminum" is the "cast aluminum alloy" in the aluminum alloy sheet industry. It is mainly made of aluminum-silicon, or added with some alloying elements for casting, that is, the product is a casting. The rough aluminum products are mostly raw aluminum. The aluminum alloy sheet is impure aluminum, which, like the pig iron, breaks hard as soon as it is knocked. The anodized film refers to a thin layer formed on the surface after oxidation of aluminum or its alloy of the anode. The thickness is 5-20 microns, and the hard anodized film can reach 60-200 microns. The anodized aluminum or its alloy improves its hardness and wear resistance up to 250-500 kg/mm 2 , good heat resistance, and the hardness of the hard anodized film is as high as 2320 K. It is excellent in insulation and resistant to attack. The wearing voltage is up to 2000V, which enhances the corrosion resistance and does not corrode in the salt fog of ω=0.03NaCl for several thousand hours. The oxide film has a large number of micropores in the thin layer, which can adsorb various lubricants, and is suitable for manufacturing engine cylinders or other wear-resistant parts; the film microporous adsorption ability can be colored into various beautiful and beautiful colors. Non-ferrous metals or alloys thereof (such as aluminum, magnesium and their alloys) can be anodized. This method is widely used in mechanical parts, aircraft parts, precision instruments and radio equipment, daily necessities and architectural decoration.
