Aluminum closure sheet coil typically refers to the aluminum coil material used in the production of caps, especially suitable for manufacturing bottle caps, jar lids, and tear-off seals. Its lightweight, formability, and excellent corrosion resistance make it an ideal choice for the beverage, pharmaceutical, and cosmetics industries.

Aluminum Closure Sheet Alloys Overview

• 8011 Alloy
  A widely used aluminum closure material, known for its excellent formability and corrosion resistance. Its high strength and good surface finish make it ideal for spiral caps and pharmaceutical caps. It is usually supplied in H14 or H16 temper and coated.
  8011 aluminum closure sheets have good formability, good ear-ring rates, and flatness, ensuring deep drawing of long bottle caps. It is commonly used for ROPP caps on wine bottles and other beverage bottles.

• 3105 Alloy
  Compared to 8011 aluminum cap sheets, 3105 H14 and H16 aluminum cap sheets offer sufficient strength to withstand gas pressure. With good processability and medium strength, they can undergo phosphochromization treatment and DOS coating, making them suitable for color coating and printing. Widely used for the production of spiral caps for carbonated drinks and mineral water.

• 1050/1060 Alloy
  Commercially pure aluminum with excellent ductility and electrical conductivity. While not as strong as alloyed aluminum, it is an ideal choice for lightweight and easily formable bottle cap applications, commonly used in cosmetics packaging.

• 5052/5182 Alloy
  A magnesium-alloyed aluminum known for its outstanding strength and corrosion resistance, with good formability and ductility. These characteristics make it ideal for producing the shapes required for can lid production. Its sealing performance effectively prevents leakage and overflow of the contents, especially suitable for beverage can lids.
