The cans are mostly made of tinplate and aluminum alloy. Among them, aluminum alloys are widely used in the packaging of cola, sprite, and small cans of tea because of their superior quality. The aluminum alloys used in can lids and can bottoms belong to Series 5 and Series 3, both of which are typical rust-proof aluminum series.
Introduction of aluminum properties for can lids:
Lightweight, heat-resistant, good conductivity, non-toxic and tasteless, good printing effect;
Resistant to acid and alkali corrosion Durable and recyclable Economical and environmentally friendly.
Aluminum standard specifications for can lids:
5052 H19 Tensile Strength/Mpa: 270-330 Elongation/%≥5 Yield Strength/Mpa: 240-300 Thickness: 0.2-0.36mm
3104 H19 Tensile Strength/Mpa: 270-320 Elongation/%≥5 Yield Strength/Mpa: 240-280 Thickness: 0.2-0.36mm
