The main products of aluminum sheet for bottle caps are 1xxx, 3xxx, and 8xxx series aluminum alloy sheets. Aluminum sheet for bottle caps is mainly used in the fields of bottle cap packaging such as wine, beverages, and cosmetics. Different series of aluminum alloys have different mechanical properties and different uses.

8011 aluminum sheet belongs to aluminum-manganese alloy, which has good forming and processing performance, corrosion resistance, weldability, and medium strength. It is often used to make bottle caps, especially white wine bottle caps, red wine bottle caps, cosmetic bottle caps, milk powder caps, beverage caps, yogurt caps, etc., to ensure the sealing and safety of bottle caps. In addition, after oxidation treatment, its surface can form a stronger oxide film, which further improves the sealing effect.

3105 aluminum closure sheet belongs to aluminum-manganese-magnesium alloy, which has good forming and processing performance, corrosion resistance, weldability, medium strength and good ductility. 3105 aluminum alloy bottle cap material also has good deep drawing performance and low earing rate, making it less likely to produce defects during processing. It is widely used in sealing packaging such as beverage bottles, wine bottles, cosmetic bottles, and medicine bottles.

Alloy state:

H14: The aluminum plate has been hardened after processing, but has not reached the highest strength state; it is suitable for occasions that pay more attention to forming performance.

H16: The aluminum plate has been further hardened after processing to achieve higher strength; therefore, it is suitable for high-strength aluminum caps.

Aluminum closure cap specifications:
