ã€China Aluminum Industry Network】 1. Excellent Corrosion Resistance Aluminum alloy doors, windows, and curtain walls are increasingly exposed to harsh environmental conditions, including industrial pollution and adverse weather, which accelerate the corrosion of anodic oxide films. This reduces their service life significantly. The AA25 grade anodized film is designed to withstand these challenges, offering a thick and durable oxide layer that provides superior corrosion resistance, making it ideal for use in demanding environments. 2. Strong Acid Resistance With the increasing occurrence of acid rain due to environmental pollution, aluminum surfaces can suffer from discoloration, loss of luster, and other damage. This not only affects aesthetics but also shortens the lifespan of aluminum products. The AA25 anodized film is highly resistant to acidic substances, effectively protecting the surface from acid rain erosion and maintaining the integrity and appearance of aluminum doors, windows, and curtain walls over time. 3. High Surface Hardness and Wear Resistance The AA25 anodized film creates a thick and dense oxide layer on the aluminum surface, significantly enhancing its hardness and wear resistance. This makes it capable of withstanding years of exposure to sandstorms, abrasion, and regular cleaning processes without losing its protective qualities. As a result, it ensures long-term durability and performance for aluminum-based architectural components. In addition to these benefits, the AA25 anodized film also offers better thermal stability and improved electrical insulation properties, further expanding its application in various construction and industrial settings. Whether used in coastal areas with high salt content or urban regions with heavy pollution, this type of coating remains a reliable choice for maintaining the quality and longevity of aluminum structures.
