| Primary body alloy | Aluminium alloy 3104 or a comparable non-heat-treatable can-body alloy | Good balance of formability, strength, corrosion resistance, and low density | A widely used alloy family supports standardized production and multi-region sourcing. |
| Lid and tab alloy | Aluminium alloy 5182 or a comparable higher-strength end-stock alloy | Higher strength than typical body stock, supporting pressure resistance and tab functionality | Separate alloy selection allows the can to be lightweight while maintaining reliable opening and sealing performance. |
| Material density | Approximately 2.70 g/cm³ at room temperature | About one-third the density of steel | Lower package weight can reduce transport weight, pallet load, and handling costs. |
| Typical empty-can mass | Approximately 12–15 g for a typical 330 ml can; approximately 15–20 g for a typical 500 ml can | Actual mass varies by can diameter, height, design, manufacturing process, and required strength | Lightweight formats are suitable for high-volume international distribution, subject to pack-design validation. |
| Wall thickness | Body wall commonly about 0.09–0.12 mm; lid stock is generally thicker, commonly about 0.20–0.30 mm | Drawn and wall-ironed construction provides a thin, rigid container | Efficient material use improves container-to-product ratio and supports cost-sensitive sourcing. |
| Can structure | Two-piece design: one drawn-and-wall-ironed body with an integrated base, plus a seamed end | Fewer major components than a three-piece metal can and a compact cylindrical geometry | Consistent dimensions simplify filling-line compatibility, case packing, and container loading. |
| Internal protective coating | A thin polymeric beverage coating, selected according to beverage chemistry and applicable food-contact regulations | Separates the beverage from the metal and helps limit corrosion, flavour interaction, and metal pickup | Coating compliance, migration testing, and regional food-contact requirements should be confirmed before purchase. |
| External coating and decoration | Base coat, printed ink system, and protective varnish or over-varnish | Supports graphics, abrasion resistance, and protection during handling and distribution | Can artwork can be localized for different markets while retaining common container specifications. |
| Light barrier | Opaque aluminium wall, with no transparent package section | Provides an effective barrier against visible and ultraviolet light | Helps protect light-sensitive beer characteristics during storage and long-distance transport. |
| Gas and moisture barrier | Metal container with a mechanically seamed end and protective internal coating | Essentially impermeable to oxygen, carbon dioxide, and water vapour when the package is intact | Supports carbonation retention and reduces exposure to oxygen throughout international distribution. |
| Thermal conductivity | Approximately 205–235 W/m·K for aluminium alloys, depending on alloy and condition | Transfers heat rapidly compared with many packaging materials | Allows fast chilling and efficient temperature response in retail refrigerators and ice-water environments. |
| Corrosion protection | Natural oxide film plus internal and external coating systems | Aluminium naturally forms a thin oxide layer; beverage compatibility still depends on formulation and coating integrity | Beverage pH, salt content, organic acids, storage temperature, and shelf life must be evaluated during qualification. |
| Recyclability | Aluminium can be recycled repeatedly without losing its fundamental material properties | Recycling aluminium typically requires about 5% of the energy used to produce primary aluminium | High recycled-content potential and established scrap value can support circular-packaging objectives. |
| Dimensional consistency | Standardized diameters, heights, neck profiles, ends, and seam specifications are available across major packaging markets | Precision forming supports repeatable filling, seaming, and palletizing | Purchasers should verify regional tooling, seam dimensions, pallet patterns, and filling-line requirements. |
| Key sourcing checks | Alloy and temper, nominal volume, dimensions, empty-can mass, coating system, end type, and decoration process | Performance depends on the complete package system rather than aluminium grade alone | Request technical drawings, food-contact declarations, seam specifications, quality certificates, migration data, and transport-test results before approval. |
