The anodized aluminum sheet metal is high end product of aluminum sheet metal through anodic oxidation processing. The so called anodic oxidation is to use a sheet metal or aluminum alloy product as an anode, and use the method of electrolysis to form an oxide film on the surface. The metal oxide film changes the surface state and properties of aluminum sheet metal, improves its corrosion resistance, enhances wear resistance and hardness, thereby protecting the metal surface. At the same time, the anodized surface of aluminum sheet metal is beautiful, it has better decoration performance, and improve finished product level.
There are a lot of micropores in the thin oxide film layer of anodized aluminum sheet metal, which can adsorb various lubricants, suitable for the manufacture of engine cylinders or other wear-resistant parts; the film micropores have strong adsorption capacity and can be colored into various beautiful and bright colors. Non-ferrous metals or their alloys (such as aluminum, magnesium and their alloys) can be anodized. And the anodized aluminum sheet can be seen as the most widely used anodized sheet metal product on the market. This method is widely used in mechanical parts, aircraft and auto parts, precision instruments and radio equipment, daily necessities and architectural decoration. For decoration industry, anodized aluminum sheet is widely used in electronic consumer goods, architectural decoration, lamps and lanterns, home appliance decoration, handicraft decoration, etc.
The anodized aluminum sheet metal has high requirements on the aluminum substrate, and the purity requirements of the aluminum material as anodized aluminum are quite high. The raw material of anodized aluminum sheet are 1060, 3003 and 5052 alloy. Of course, the higher the purity of aluminum sheet metal, the higher the price of anodized aluminum sheet, which is one of the reasons for the high price of anodized aluminum sheet.
