               About the anodized aluminum alloy enclosure

In today’s market, aluminum alloy enclosures are widely used in both life and industrial products. Aluminum alloy enclosure products can be seen everywhere on the street, and the popularity of aluminum alloy enclosures is increasing day by day; aluminum alloy enclosures can adapt to a certain environment or achieve certain functions, and enterprises will also choose different processes to treat the surface of the aluminum enclosure, such as Anodizing, electroplating, spraying, micro-arc oxidation, etc. Among them, the anodizing process is a widely used process in the processing of aluminum alloy enclosures. It can form an anodized mold with a certain thickness, strength, and aesthetics on the surface of the aluminum alloy enclosure. What are the characteristics of adding anodizing process to aluminum alloy enclosure processing?


Anodizing refers to the process in which aluminum and its alloys form an oxide film on aluminum products (anode) under the action of an applied current under the corresponding electrolyte and specific process conditions. Unless otherwise stated, anodizing generally refers to sulfuric acid anodizing. In order to overcome the defects of surface hardness and wear resistance of aluminum alloys, expand the scope of application and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloys. Anodizing technology has been widely used, and anodized aluminum enclosures have also been widely used. 


After the aluminum alloy enclosure is anodized, a layer of anti-corrosion, wear-resistant, and beautiful oxide film will be formed on the surface. The characteristics of the oxide film also establish the position of anodization in the surface treatment process. The aluminum alloy housing is anodized with a protective “coating”. Since the chemical properties of the anodized film are very stable in the natural environment, it can provide anti-corrosion protection for the aluminum alloy enclosure. At the same time, the anodized film has high hardness, low roughness, and a smooth surface, which greatly improves the wear resistance of the aluminum enclosure. If various organic and inorganic dyes are added during the anodizing process, the anodized film is colored, which gives the anodized aluminum enclosure a beautiful appearance.


The anodizing process is very beneficial to the aluminum alloy enclosure, but when doing this process, some directional silver-black streamline stripes are often formed on the surface of the aluminum alloy enclosure. These streaks are caused by certain defects and impurities on the surface of the aluminum alloy die casting during the anodizing process. The current of anodizing is unevenly distributed on the surface of the product. In some places the current is small and in some places the current is large. The flow rate of the electrolyte will be slowed down at the depression and the flow rate at the tip will be increased. The effect of anodizing is uneven, and black stripes appear on the surface of the aluminum alloy enclosure, so be very careful when polishing the aluminum alloy enclosure.
