Aluminum alloy has low density but relatively high strength, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity, and corrosion resistance. It is widely used in industry and its usage is second only to steel. Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties, and corrosion resistance. Aluminum profile is a kind of material that is made into various shapes and various surface treatment carvings according to the requirements of building design. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts is increasing, and the weldability of aluminum alloy is also studied in depth. At present, aluminum alloy is the most widely used alloy.
In the natural environment, aluminum will naturally form a thin oxide film, which has certain protective properties. However, the surface of this untreated aluminum is very susceptible to physical damage and chemical corrosion. The process of using aluminum or aluminum alloy profiles as anodes, placing them in an electrolyte solution for energization, and using electrolysis to form an aluminum oxide film on the surface is called anodizing of aluminum and aluminum alloys. After anodic oxidation treatment, the aluminum surface can generate an oxide film of several micrometers-hundreds of micrometers. Compared with the natural oxide film formed by aluminum alloy, its corrosion resistance, wear-resistance, and decoration are significantly improved and improved.
The so-called aluminum anodized is an electrolytic oxidation process in which the surface of aluminum and aluminum alloys is usually transformed into an oxide film, which has protective, decorative, and other functional properties. The anodization of aluminum starting from this definition includes only the part of the process of generating anodized film. Anodizing can significantly improve the corrosion resistance of aluminum alloys, increase the surface hardness and wear resistance of aluminum alloys, and have good decorative properties after the appropriate coloring treatment.
