Alloy 3105 aluminium sheet

About 3105 Alloy aluminium sheet

3105 aluminum sheet is a typical stamping material. Its aluminum content is up to 98%, which can be classified as pure aluminum alloy. Compared with 1xxx aluminum that contains about 99% aluminum, it has slightly increased strength. Similarly, 3105 aluminum alloy cannot be strengthened by heat treatment, but its corrosion resistance, formability and welding characteristics are also excellent. "Compare with 8011 closure sheet, 3105 aluminum sheet has enough strength, so it is stronger enough to bear the gas pressure, so it is widely used for making screw cap for gas liquid bottle, such as soda water and carbonated wine.."

We could treat 3105 aluminum sheet with phosphoric acid chromated, and DOS coated, printed with different colors, on the basis of our plain sheet.
We control the materials composition, rolling temperature and time,and annealing temperature to product optimal materials to meet client’s performance needs, such as its opening capability and earing rate.
With our good flatness and squareness, we could prevent color gapping, unevenness or print misalignment during printing.

8011 Aluminium sheet is used for the bottle cap market. Using a unique rolling technology, Haomei supplies aluminium sheets ideally suited to manufacture the caps for long neck wine bottles, extremely deep drawn and decorated closures, plus a range of pilfer proof caps for beverage bottles, soft drink, juice, isotonic beverage, energy beverage, and other products, such as the 30x60 mm specifications are often used in the wine and spirits segment.


Best class formability, flatness, rectangularity and unwavering surface properties.

Stable deep drawing quality to make sure highest rates of materials rate.

Various processes and technologies can meet the requirements of various surfaces.

Packaging of Aluminium pp cap Sheets

Alloy 3105 Aluminum products of Haomei Aluminum meet the export standard. Plastic film and brown paper can be covered at customers’ need. What’s more, wooden case or plywood box is adopted to protect products from damage during the delivery. There are two kinds of packaging, which is eye to wall or eye to sky. Customers can choose either of them for their convenience. Generally speaking, there are 2 tons in one package, and loading 18-22 tons in 1×20′ container, and 20-24 tons in 1×40′ container
