Aluminum's inherent lightweight and corrosion-resistant properties provide a solid foundation for its widespread application, while targeted surface treatments can further unlock its potential. From 1-series pure aluminum to other series of aluminum alloys, appropriate surface treatments can not only improve durability and functionality but also enrich decorative effects, allowing aluminum products to shine in fields such as construction, packaging, and electronics.
Anodizing: The "Protective Shield" for Aluminum Surfaces
Anodizing is one of the most widely used aluminum surface treatment technologies, which forms a dense and porous oxide film on the aluminum surface through electrochemical reactions. This film not only enhances corrosion resistance but also provides a good base for coloring, making it suitable for both functional and decorative scenarios.
Take 1-series aluminum sheets (e.g., 1050, 1100) for kitchenware and food packaging: a thin anodized film (5-10μm) ensures food safety while effectively preventing surface oxidation and discoloration. For 3-series aluminum coils used in coastal building exteriors, a thick anodized layer (15-25μm) provides strong resistance to salt spray corrosion, increasing service life by over 3x compared to untreated aluminum. Additionally, the porous structure of the anodized film allows for dyeing in diverse colors, making it a top choice for decorative aluminum products like architectural ceilings and electronic casings.
Color coating: Colorful and Durable "Outerwear"
Color coatings utilize different paints (such as polyester, silicone polyester, polyvinylidene chloride, and polyvinyl chloride plastisol) depending on the application requirements. Using techniques like roller coating and powder coating, the paint is adhered to the aluminum surface to form a robust coating. Color-coated aluminum is renowned for its rich colors, strong adhesion, and excellent weather resistance, and is widely used in outdoor products and home appliances. For example, 3-series aluminum roofing tiles used in industrial plants and residential roofs often employ powder coating, providing protection against UV radiation and acid rain corrosion, maintaining over 90% color retention even after 10 years of outdoor use.
Embossing: Functional Texture for Practical Scenarios
Embossed aluminum sheets used for industrial platforms and stair treads enhance safety through their non-slip texture, while the rough surface conceals minor scratches that occur during use. Orange peel textured embossed aluminum sheets used for furniture upholstery and wall cladding add warmth to spaces with their soft texture, and their processing cost is lower than anodizing, making them suitable for large-scale decorative projects. Furthermore, embossed aluminum sheets offer better rigidity than ordinary aluminum sheets, reducing deformation during transportation and installation.
