5182 H19 aluminum coil strip for pull rings
The pull-tab on cans, a vital component, primarily serves to assist consumers in effortlessly opening the cans. When selecting materials for the pull-tab, it is essential that it possesses excellent forming and processing capabilities, corrosion resistance, weldability, and adequate strength to guarantee its stability and reliability throughout manufacturing, transportation, and usage.
The primary material used for can pull-tabs is the 5182 H19 aluminum alloy. This alloy not only exhibits robust oxidation and corrosion resistance but also withstands high pressure and temperature conditions, thereby ensuring the cans' seal integrity and safety. Aluminum alloy pull-tabs boast a low density, high strength, ease of forming, and are recyclable, aligning with modern environmental protection principles.
