Colored Aluminum-Shan Dong Jie Han
Technical Principles and Processes
PVD Technology: It deposits an ultra-thin film of metallic or non-metallic compounds on the aluminum surface. By controlling the film’s composition and thickness, a wide range of colors can be achieved—from gold and silver to black and blue—featuring vivid hues and high wear resistance.
Chemical Oxidation: This method forms a colored oxide film on aluminum via electrolytic or chemical processes. The color is stable, but its wear resistance is slightly lower compared to PVD-treated aluminum.
Electrophoretic & Spray Coating: These two methods are more suitable for large-scale production. They realize efficient coloring by uniformly adhering pigment particles to the aluminum surface.
Application Scenarios
Architectural Decoration
Due to its light weight, corrosion resistance, and aesthetic appeal, colored aluminum plates are widely used in building curtain walls, roofs, doors, and windows, adding a unique visual effect to architectural designs.
Advertising Signs
With good processability and weather resistance, colored aluminum serves as an ideal material for manufacturing outdoor billboards, light boxes, and signboards.
Electronic Products
As consumer electronics attach greater importance to appearance design, colored aluminum is adopted for casings of mobile phones, laptops, and other devices, enhancing the products’ sense of fashion and technology.
Auto Parts
Colored aluminum is applied to auto components like wheel hubs and decorative trim. It not only reduces vehicle weight, but also improves the car’s distinctiveness and aesthetics through color design.
Industry Standards and Selection Criteria
Notes
Storage and Transportation
Colored aluminum should be kept away from acid and alkali substances. It needs to be stored in a dry and well-ventilated environment, and protected from scratches and collisions during transportation.
Processing and Installation
Specialized tools must be used during processing to avoid damaging the surface coating. During installation, ensure the base material is flat to guarantee the adhesion and appearance of the colored aluminum.
Maintenance and Upkeep
Regularly clean the surface of colored aluminum and avoid using corrosive cleaning agents to extend its service life.
