Aluminum Coil strip Sheet for beverage cans

Cans are the most commonly used beverage packaging materials in life today. The Aluminum Coil strip Sheet for beverage cans is mainly composed of three aluminum alloys with different compositions: 3004 alloy can body, 5052 alloy can lid, and 5182 alloy pull ring. Aluminum alloy is the key to making cans. The problem of aluminum body is that the can body is not formed and the ring of the can lid cannot be opened.
 


The can body of the Aluminum Coil strip Sheet for beverage cans mainly uses 3004 alloy, and 3004 alloy is a variant alloy of 3003, which has good formability, weldability, and corrosion resistance. It is mostly used for processing and requires good formability and high resistance. Corrosive and solderable products. Because aluminum itself has good oxidation resistance, it is used in cans for cans to prevent oxidation and corrosion of carbonated beverages on cans.
 
　The can lid of the Aluminum Coil strip Sheet for beverage cans is 5052 alloy, and the pull ring is 5182 alloy. The 5052 alloy and the 5182 alloy are both aluminum-magnesium alloys. They have good corrosion resistance, good weldability, good cold workability, and moderate strength. After polishing, their surfaces are very bright. However, the 5182 alloy has a higher magnesium content than the 5052 alloy, and a small amount of silicon is added, so the weldability is better than the 5052 alloy. Therefore, the 5052 alloy is mostly used for can lids, and the 5182 alloy is mostly used for pull rings.
