Causes and solutions to the problem of color spots on anodized aluminum plates

As the core material for building curtain walls, electronic equipment and high-end home furnishings, anodized aluminum plates are favored for their advantages such as lightweight and corrosion resistance. However, the problem of color spots has long plagued the industry – uneven oxide film, local corrosion, sealing defects, etc., directly lowering the product grade and even causing customer complaints. The formation of color spots on anodized aluminum plates may involve multiple aspects such as materials, processes, equipment and environment. ◆ First, in terms of materials, uneven aluminum alloy composition will lead to different oxidation reaction rates in different areas, resulting in color spots. ◆ Secondly, incomplete surface pretreatment, such as oil, oxide scale, dust, etc., will cause uneven growth of the oxide film and form color spots. ◆ In addition, improper control of process parameters such as oxidation tank liquid composition, temperature, current density, oxidation time, etc. will also lead to the appearance of color spots. What should be paid attention to when selecting and processing aluminum alloy materials? First of all, aluminum alloy materials with uniform composition should be selected. When purchasing, the quality inspection report of aluminum plates and aluminum coils should be checked to ensure uniform distribution of...

Cold-Rolled Aluminum Plate Vs Hot-Rolled Aluminum Plate

Aluminum plates, whether cold-rolled or hot-rolled, are the most common aluminum plates we have at present. Because of their different uses, we divide aluminum plates into cold-rolled aluminum plates, such as the representative product 1060 aluminum plate, followed by hot-rolled aluminum plates such as 5052 aluminum plates. However, there are actually many differences between cold-rolled and hot-rolled aluminum plates. Differences between cold-rolled and hot-rolled aluminum plates 1. Appearance difference The difference in the surface between cold-rolled and hot-rolled aluminum plates. From the appearance alone, it can be seen that the surface of hot-rolled aluminum plates will be a little gray and black, and the brightness of cold-rolled aluminum plates may not be that much. The reason for this is that hot-rolled aluminum plates are often made of alloys, especially manganese, magnesium, silicon and other metals, which will cause the surface of aluminum plates to be gray and black, so the surface of the two is grayer than that of hot-rolled plates, while cold-rolled ones will not. Usually, the surface brightness of hot-rolled plates is better than that of cold-rolled plates, but this should also be compared with the thickness of the aluminum plate. 2. Performance difference The difference between cold...
