Is 3003 aluminum coil used for beverage cans
3003 aluminum coil ranks top in popularity among Al-Mn aluminium sheet rolls which serve as an excellent material for beverage cans. 3003 used to be used in beverage cans. Due to the manganese alloy element, it shows excellent anti-rust properties. Aluminum will form an oxide film on the outside in the air, namely aluminum oxide, which prevents aluminum from being oxidized even at the high temperature. After being made into beverage can bodies, 3003 has this oxide film outside to protect the can body from being eroded by contained liquids. In addition, 3003 is small in density, light in weight and easy to recycle. And it was the maturest aluminium alloys suitable for beverage cans in the early years. All these made 3003 aluminum coil catch on in the can industry. Unexpectedly, however, current lists of regular can materials exclude 3003. Why? The top reason is that more substitutes with better properties have been developed. 3004 aluminum coil, for example, are stronger in ...
