Aluminum cans boast benefits such as being lightweight, heat-resistant, highly conductive, odorless, non-toxic, and offering exceptional print quality. Additionally, they are resistant to acid and alkali corrosion, durable, recyclable, cost-effective, and eco-friendly. Currently, aluminum alloy serves as the primary material for can production.
The aluminum alloy cans are crafted from various alloys depending on their part. Typically, the lid (or bottom) of the can utilizes 5052 or [b]3104 aluminum sheet/strip[/b], while the pull ring is made from 5182 aluminum sheet.
