3105 8011 for Bottle Cap Used Hot Rolled Aluminium Coil
Last Updated :Jan. 17, 2025
3105 and 8011 aluminum alloys are widely used as hot rolled aluminum coils in the production of bottle caps, especially for beverage bottle caps, food bottle caps, wine bottle caps, beer bottle caps, and others.
Comparison between 3105 and 8011 Aluminum Alloys
- 3105 aluminum alloy, with its strong corrosion resistance and good formability, is more suitable for applications that require excellent corrosion resistance but low strength, such as common soft drink bottle caps and food bottle caps.
- 8011 aluminum alloy, due to its excellent surface treatment performance and high strength, is commonly used for bottle caps that require coating or decoration, such as pharmaceutical bottle caps or high-end cosmetic bottle caps.

3105 Aluminum Alloy in Bottle Caps
As a bottle cap material, 3105 aluminum alloy, due to its excellent ductility and corrosion resistance, is commonly used as the base material for beverage bottle caps, beer bottle caps, and other food bottle caps. Its relatively light weight and oxidation resistance make it an ideal choice.
This alloy is typically processed through hot rolling, forming thin sheets or coils, which meets the needs of large-scale production.
8011 Aluminum Alloy
8011 Aluminum Alloy Composition and Properties
- Main Elements: Primarily aluminum, with small amounts of iron and silicon.
- Alloy Series: Belongs to the 8000 series of aluminum alloys, known for good deep processing performance and high oxidation resistance.
- Strength: Although its strength is slightly lower than some high-strength aluminum alloys, its good weldability and corrosion resistance make 8011 alloy an important material in the bottle cap industry.
- Surface Treatment: 8011 aluminum alloy has good surface treatment performance, suitable for coating processes, and ensures long-term corrosion resistance.
- Corrosion Resistance: Its excellent corrosion resistance, especially in humid environments, makes it suitable for food and beverage packaging.
8011 Aluminum Alloy in Bottle Caps
8011 aluminum alloy is widely used in the bottle cap industry, especially in the production of food bottle caps, cosmetic bottle caps, pharmaceutical bottle caps, and others.
Its good surface flatness and machinability allow it to be easily formed in the hot-rolled state, ensuring stable coating adhesion and appearance quality during surface processing.
8011 aluminum alloy is also suitable for the manufacture of special coated bottle caps, meeting the diverse needs of customers for the appearance and performance of bottle caps.
