Parameters Of Color Coated Aluminum Foil

Colored-Coated Aluminum Foil Substrate

Colored-coated aluminum foil undergoes color treatment through coating technology. The production of aluminum foil involves pressing aluminum into extremely thin layers to meet various thickness requirements, typically ranging from 0.006 millimeters to 0.2 millimeters. Common grades of aluminum foil include 13003, 8011, 1050, each with its own characteristics:

• 3003 Colored-Coated Aluminum Foil: Contains a small amount of manganese, enhancing aluminum's strength and corrosion resistance. Widely used in fields requiring toughness and durability, such as cookware and building materials.
• 8011 Colored-Coated Aluminum Foil: Used extensively in manufacturing hydrophilic aluminum fins. These fins play a crucial role in heat exchangers, significantly improving heat transfer efficiency. The surface coating of hydrophilic aluminum fins enhances aluminum's surface hydrophilicity, aiding more effective heat transfer in radiators and cooling systems.

Through color coating, aluminum foil not only provides various colors and patterns but also enhances its durability and aesthetic appeal. This treatment typically involves applying multi-layered colored coatings, increasing the foil's decorative and functional properties. Colored-coated aluminum foil substrates are commonly used in architectural decoration, signage, packaging materials, and other fields.
