Chongqing industrial aluminum profiles are characterized by high purity and good corrosion resistance. As we all know, pure aluminum reacts with oxygen in the air, and a thin dense natural oxide film will be produced on the surface of aluminum, which is much faster and thicker than other metal oxide films, thus preventing the corrosion of harmful gases and moisture in the air and playing a protective role.
Chongqing industrial aluminum profile is specially created aluminum, with distinctive characteristics and surface treatment of the product. So what is the function of surface treatment? Because the corrosion resistance of pure aluminum is good, but its mechanical strength is poor, which restricts the application of aluminum to a certain extent. Therefore, people add some other metals such as magnesium, copper and zinc into aluminum to make various types of aluminum alloys. The mechanical strength of aluminum alloys is high, which greatly improves the mechanical strength of aluminum and expands its application scope. Although the mechanical strength of aluminum alloys is high, their corrosion resistance is worse than that of pure aluminum, so they may be corroded due to oxidation. This requires powder coating to protect aluminum alloy profiles. Aluminum alloy has been widely used in doors, windows, curtain walls and other products of buildings for many years because of its small specific gravity, easy processing and high mechanical strength.
