8011 H14 aluminum foil is a hot-rolled aluminum anti-theft cap material, made from 8011 aluminum alloy and processed through work hardening to form a high-strength aluminum coil. The main alloying elements are aluminum (Al), iron (Fe), and silicon (Si), which provide excellent mechanical and chemical properties. The H14 state indicates that the aluminum coil has undergone work hardening, achieving high strength and medium plasticity, suitable for bottle cap stamping and stretching. The typical thickness range is 0.15-0.27 mm, and the width range is 330-1000 mm, meeting various design and production requirements for bottle caps.
Advantages of 8011 H14 Lacquer Aluminum Coil in Aluminum Alloy Bottle Cap Manufacturing
1. Lightweight and High Strength: The aluminum coil material is light yet strong, reducing the weight of the bottle cap, lowering transportation costs, and ensuring structural integrity during the stamping process.
2. Excellent Sealing Performance: Lacquered aluminum coils provide superior sealing, effectively preventing the penetration of gases, liquids, and microorganisms, ensuring the quality and safety of the packaged contents.
3. Durability and Corrosion Resistance: The coating of 8011 H14 lacquer aluminum coil effectively resists oxidation, rust, and moisture, keeping the bottle cap looking new for a long time.
4. Excellent Processing Performance: In the H14 state, the aluminum coil is not prone to cracking during stamping, stretching, and edge forming, making it suitable for various bottle cap production processes.
5. Environmental Protection and Recyclability: Aluminum materials can be recycled, reducing resource waste and enhancing the company's environmental image.
