Aluminum can body material

Material Properties

Aluminum alloys possess the following unique properties:

• Low density andhigh strength-to-weight ratio

• Excellent electrical and thermal conductivity

• Superior Corrosion Resistance

• Widely used in food packaging, maritime and aviation industries, automotive, petrochemical, telecommunications, nuclear energy, and aerospace technologies.

Aluminum alloy sheet can bodies manufactured using this process:

• Dense structure with no shrinkage cavities, porosity, or cracks.

• Optimize mold filling and solidification via numerical simulation to minimize casting defects

Product Benefits

Modern beer, beverage, and food cans must meet the following requirements:

1. Protect packaging from external damage caused by light, gases, and mechanical forces.

2. The tank itself is neither damaged by nor damages the packaging.

3. Multiple tank specifications available

4. The container design must capture consumer attention.

5. Consumer-friendly food access

6. Fits standard filling and loading equipment

7. Economical and practical

Application Areas

Aluminum can body material meets all requirements:

• Opaque and sealedBlocks air, water vapor, and other gases

• Resistant to all common food preservation methods (freezing, dehydration, heat sterilization)

• Neutral & Odorless, inhibits bacterial growth

• Chemical resistance of dry packaging and wet packaging with near-neutral pH (enhanced after coating)

• Superior formability for versatile container sizes and shapes

• Seamless structureSeamless on sides and bottom, eliminating potential weak points common in standard containers.

• Enhance creep resistance of pressurized beverage can sidewalls

• Natural silver-white finish, suitable for spray painting and decoration.

• Easy-open can design: tear-off lid for solid foods, removable cap for liquids.

• Rigidity comparable to tinplate cans; compatible with high-speed automated filling lines (requires equipment modifications for magnetic dependency, etc.)

• Lightweight design (seamless bottom reduces weight)

• Can wall thickness has been reduced to0.114–0.152 mm

• Gas strengthening mechanism：

  • Carbonated beverages enhance sidewall mechanical performance through internal pressure.

  • Non-carbonated beverages (juices, drinking water, etc.) have reinforced side walls by injecting liquid nitrogen, which expands 700 times upon vaporization.
