After the aluminum and aluminum alloy of Changshu Yongxiang aluminum plating Co., Ltd. are treated by conductive aluminum oxidation process, the aluminum oxide film obtained still has excellent conductivity, which is its unique performance, and the protective and decorative performance of the film is also very good. The color of the film on the surface of pure aluminum is more elegant than the rainbow passivation film of zinc layer, with shallow and uniform fine grain color, It is a process with great application prospect and popularization value.

Changshu Yongxiang aluminum plating Co., Ltd. aluminum and aluminum alloy conductive aluminum oxidation process is easy to operate and does not need special equipment. In recent years, the understanding that the conductive aluminum oxide film is easy to absorb organic coatings and has good adhesion has been further improved. Therefore, the application scope used as coating (electrophoresis and painting) substrate has been gradually expanded.

Specific details needing attention in the pretreatment process of Changshu Yongxiang aluminum plating Co., Ltd; Aluminum materials are extremely unstable in the air and are easy to produce aluminum oxide films that are difficult to identify with the naked eye. Due to the different processing methods of aluminum parts, such as casting molding, or direct shearing of rolled plates, or fine machining molding, or forming through different processes and then heat treatment or welding, the surface of the workpiece will show different states and different degrees of dirt or traces, Therefore, in the pretreatment process, the pretreatment process method must be selected according to the actual situation of the workpiece surface.
