Aluminum profiles are used in various aspects of daily life, including frames, equipment covers, and workbenches on assembly lines. Because the surface of aluminum profiles undergoes anodizing, they are aesthetically pleasing and corrosion-resistant. The reasons for this anodizing process will be explained in detail below.
First, aluminum profiles have decorative properties. After anodizing, a protective film forms on its surface, which is highly transparent. Adding other dyes creates colored oxide films, which not only serve as decoration and corrosion protection but also achieve a level of performance comparable to ceramic tiles.
Second, aluminum profiles are non-conductive. While aluminum itself is conductive and cannot be used in electrically charged frames, anodizing eliminates this conductivity.
Therefore, electrically charged equipment can be constructed using aluminum profiles, blocking many potential hazards and reducing the damage caused by electric current to objects and property. The oxide film on aluminum and aluminum alloy products after anodizing has a high resistance, thus enhancing the electrical insulation of certain parts of the product.
Third, aluminum profiles are corrosion-resistant. The film formed by anodizing is stable enough in the atmosphere, so it can be used for protection.
