Color of aluminum

Aluminum can be made into gradient colors through a variety of processes, including but not limited to anodizing, electrophoretic coating and painted gradient aluminum veneer processing.
Anodizing is a treatment method that changes the appearance and performance of aluminum alloys by forming an oxide film on their surface. In the production of gradient colors, anodizing can achieve a gradient effect by masking part of the surface and then anodizing different parts with different colors.
The specific process flow includes polishing, sandblasting, wire drawing, degreasing, masking, anodizing, sealing and other steps. The advantages of this method include improving strength, achieving any color except white, and achieving nickel-free sealing to meet the requirements of nickel-free in specific countries. The technical difficulty lies in improving the yield of anodizing, which requires the appropriate amount of oxidant, temperature and current density.
Electrophoretic coating is suitable for materials such as stainless steel and aluminum alloys. By processing in a liquid environment, surface treatment of various colors can be achieved while maintaining the metallic luster and enhancing the surface performance, and having good anti-corrosion performance. The process flow of electrophoretic coating includes pre-treatment, electrophoresis, drying and other steps.

Its advantages include rich colors, no metallic texture, can be combined with sandblasting, polishing, brushing and other treatments, processing in a liquid environment can achieve surface treatment of complex structures, mature technology and mass production.

The disadvantage is that the ability to conceal defects is average, and the pre-treatment requirements are high.
The painted gradient aluminum veneer is processed by using fluorocarbon paint through a special roller coating process, adding new materials, so that the aluminum plate has a gorgeous and soft color like metal, presenting different colors at different angles, forming a flowing visual aesthetic decoration. This treatment method takes advantage of the excellent performance of the fluorocarbon coating, and there are dozens of options for the base color. It can be processed with a variety of alloy materials according to thickness and technical requirements.
Aluminum can achieve a gradient color effect through a variety of processes such as anodizing, electrophoretic coating and painted gradient aluminum veneer. Each method has its specific process and technical characteristics, suitable for different application scenarios and needs.
