In the field of metal packaging for beverage cans, specifically, 5052 and 5182 aluminum sheet coils are primarily employed in the production of can end ring-pulls, Beer ends, drink lids, beverage lids, beer lids, aluminum can lids, aluminum covers, and Pop Can Covers.
Chalco's best-selling aluminum materials for beverage cans
As is widely known, beverage cans consist of three integral components: the can body, can lid, and pull-tab ring. The can body is formed through high-speed stamping on deep-drawing presses, resulting in a seamless can body. The can lid is later attached through a curling process, facilitated by the excellent ductility of 3104 aluminum, ensuring a secure connection between the lid and the can body.
Currently, the most commonly used aluminum alloys for overall beverage can manufacturing are 3003-H14, 3104-H19, 5182-H48, and 5052-H48 aluminum can alloys. Their specific applications are outlined as follows:
3004 3104 aluminum coil strips for can body
3004 3104 aluminum alloy coils are the primary materials used for can bodies. 3104 belongs to the Al-Mn alloys category. The addition of the main alloying element, manganese (Mn), enhances the mechanical properties of the alloy without compromising its corrosion resistance. The most commonly used 3104-H19 aluminum coil for can bodies offers exceptional deep-drawing capability and robust corrosion resistance.
5052 5182 aluminum sheet coils for can lids
5052 5182 aluminum alloys are the most widely used materials for can lids. These 5xxx series aluminum-magnesium alloys offer excellent ductility and high strength, allowing easy production of various lid sizes. The 5052-H48 temper, with its moderate strength, can withstand the stresses of carbonated beverages and other gas metal packaging, making it an ideal material for lid production.
5182 aluminum sheet coils for can pull tabs
5182 aluminum alloy is the most representative material for pull-tab manufacturing. Classified under the 5xxx series of aluminum-magnesium rust-resistant alloys, 5182 aluminum sheets have a magnesium (Mg) content ranging from 4% to 5%. They exhibit excellent corrosion resistance and processability, along with high tensile strength, making them well-suited for aluminum pull-tab production with specific hardness requirements.
