For more detailed information including pricing, customization and shipping.
3105 aluminum sheet is an ideal material for making bottle caps, and is very suitable for making wine bottles, beverage bottles, soda water, juice, energy drinks and high-end cosmetics bottle caps. The main thickness of 3105 aluminum sheet for bottle caps is 0.15-0.30mm, and the tempers are H14, H16, H24, etc.
Compared with the 8011 aluminum plate for bottle caps, the 3105 aluminum sheet for screw caps has enough strength and can withstand larger gas pressure. 3105 aluminum sheet is widely used to make screw caps for vapor and liquid bottles, such as soda water and carbonated wine, etc. Also, the 3105 aluminum sheet for bottle caps can be printed in different colors and decorated with different styles of wine bottle caps and other bottle caps after being treated with chromium phosphate or DOS coating.
