Aluminum Sheet Coil For Can Caps
3104 H48 aluminum coil is commonly used to produce can lids for beverage cans, beer cans, ropp bottle and other can caps.
Currently, there are 3003, 3004, 3005, 3104, 3105, 5005, 5052, 5182, 5754 and 5454 aluminum alloys used for the overall manufacturing of aluminum cans. Among them, the most commonly used are 3104-h19, 5182 h19 and 5052-h19 aluminum coil.
3104 Aluminum for Lids
3004 aluminum alloy belongs to Al-Mn alloy. The addition of main alloy element Mn, not only improves the mechanical properties, but also doesn't reduce the corrosion resistance of the alloy. 3104-h19 aluminum coil has excellent deep impact and strong corrosion resistance. The plain aluminum coating/oil can play an excellent oxidation and corrosion resistance. Besides, 3104 aluminum cans alloy all can be well used for thinning and stretching, with low earing ratio, good printing effect, reduced material consumption and reduced batch purchase cost.
3104 aluminum sheet coil tensile strength ≥275Mpa, the elongation is up to 20%, and the earing ratio(E)≤4%.
3104 aluminum is usually delivered in big roll in packages of aluminum coil, or it can be slit into aluminum strip on request and delivered in the desired width.
Chemical Composition ratio (For Reference)
Alloy | Manganese | Magnesium | Iron | Silicon | Copper | Zinc | Titanium | Vanadium | Gallium | Residuals | Aluminum |
3104 | 0.8-1.4 | 0.8-1.3 | ≤0.8 | ≤0.6 | 0.05~0.25 | ≤0.25 | ≤0.1 | ≤0.05 | ≤0.05 | ≤0.15 | 95.1-98.4 |
Properties of 3104 H48 aluminum coil
Physical Properties
The physical properties of 3104 H48 aluminum include light weight, high reflectivity, good thermal conductivity and good electrical conductivity.
Mechanical Properties
It is strong, malleable and stretchable. It is suitable for deep drawing processes, stretching and forming without cracking or tearing.
Corrosion resistance
3104 H48 aluminum also has good corrosion resistance and can be applied to the packaging of water or other corrosive objects. It can also be coated with a protective layer, such as lacquer or paint, to further improve its corrosion resistance.
5052/5182 Aluminum for Lids
For beverage aluminum lids with the largest demand, including beer and carbonated beverages such as carbonated acid and alkali, 5182 h19 aluminum alloy was the most used, with common specifications of 0.249*827.89mm, 0.27*946.5mm, 0.22*911mm, etc. And for 5052-h19 aluminum cans alloy, was used for mixed congee and other non-vapor food aluminum lids, with common specifications of 0.25*803mm and 0.25*721.8mm,etc. Most notably, Mingtai Al. has the mature aluminum cans alloy for lids production technology, which can ensure the 5052, 5182 aluminum alloy sheet version of the flat, excellent processing performance, and provide the original warranty!
5182 Aluminum for Ring Pull of Cans
In addition, 5182 aluminum cans alloy is also the most representative material for ring pull manufacturing. 5182 aluminum sheet belongs to 5 series Al-Mg antirust alloy, and its main composition Mg content can reach 4% ~ 5%. So, 5182 h19 aluminum sheet for ring pull has excellent corrosion resistance and processability, with a common thickness of 0.279--0.406mm. Here, Mingtai Al. introduces advanced grinding equipment to ensure the flatness of the sheet and the thickness tolerance of ± 0.005mm!
