Aluminum alloy sheet
Introduction to Aluminum alloy sheet:
With the development of modern industry, the application of light metal materials has become increasingly widespread. Aluminum and Aluminum alloy sheet has a series of advantages such as low density, strong electrical and thermal conductivity, excellent mechanical properties, and good workability, and have been widely used in various sectors of the national economy.
Features of Aluminum alloy sheet:
In the construction field, 98% of high-rise buildings in Japan use Aluminum alloy sheets as door, window, and wall decoration. Compared with ordinary wooden doors and windows and steel doors and windows, aluminum alloy doors and windows have the characteristics of lightweight, fewer materials, beautiful appearance, corrosion resistance, and convenient maintenance. Although the cost is 3 to 4 times higher than ordinary wooden doors and windows, the long-term maintenance cost is low. It has broad development prospects.
Aluminum alloy sheet oxide film protection:
In the atmosphere, the surface of an Aluminum alloy sheet interacts with oxygen to form an oxide film, but the film is thin (3×10-3 ~5×10-3μm), loose and porous, amorphous, uneven and discontinuous, Cannot be used as a reliable protective-decorative film. At present, anodizing or chemical oxidation is widely used in the industry to form an oxide film on the surface of Aluminum alloy sheet parts to achieve the purpose of protection and decoration.
The difference between aluminum alloy sheet chemistry and anodized film:
The thickness of the oxide film obtained by chemical oxidation treatment is generally 0.3~4μm, and its softness, wear resistance, and corrosion resistance are all lower than the anodic oxide film. The thickness of the oxide film obtained by anodizing treatment is generally 5-20μm, and the thickness of the hard anodizing film can reach 60-250μm. The film layer is firmly bonded to the base metal and has high corrosion resistance, wear-resistance, and hardness. The porous oxide film has a strong adsorption capacity and is easy to be colored with organic dyes. At the same time, it also has the characteristics of good insulation performance, strong heat insulation, and heat resistance.
Uses of Aluminum alloy sheet:
In summary, after the aluminum alloy sheet is anodized, the oxide film formed on its surface has good protection-decoration properties. Therefore, it is widely used in aviation, electrical appliances, electronics, machinery manufacturing, and the light industry.
