The performance of can lid material 3104 and 5052 aluminum coils meets the standards

Can lids are usually made of aluminum alloy, and 3104 and 5052 are two common aluminum alloy materials. They have different performance characteristics in the manufacture of can lid materials. Here are some of their main properties:

3104 Aluminum coils for aluminum can body

3104 aluminum coil is mainly used for cans, such as beverage cans, beer cans, juice, etc.

• Strength: 3104 aluminum alloy has high strength and is suitable for the manufacture of cans.
• Corrosion resistance: It has good corrosion resistance, which helps ensure that the can is not affected by the external environment during use.
• Processability: 3104 aluminum coil is easy to process into various shapes and is suitable for the forming of cans.
• Weldability: It has good weldability and facilitates connection during the manufacturing process.
• Chemical composition: Including aluminum (Al), manganese (Mn), magnesium (Mg), silicon (Si), iron (Fe), copper (Cu) and other elements. Has good antioxidant and corrosion resistance.

5052 Aluminum coils for can lid

5052 H19 H48 H49 aluminum coil is mainly used for can lids, and 5052 H48 aluminum coil strip is used for beverage and food lids without internal pressure.

• Strength: 5052 aluminum alloy has high strength, provides good structural properties, and is suitable for the manufacture of can lid materials.
• Corrosion resistance: It has high corrosion resistance, which helps ensure that cans are not susceptible to chemical corrosion during use.
• Formability: 5052 aluminum coil has good formability and is suitable for deep drawing and forming processes of can lid materials.
• Weldability: It has good weldability and is easy to make welding connections during the manufacturing process.
• Chemical composition: Mainly contains aluminum (Al), magnesium (Mg), chromium (Cr), manganese (Mn), and has good corrosion resistance.

Cans can be used for packaging beverages, food cans, rice pudding, and pet cans. The materials used to make cans are mostly aluminum alloys. Their performance meets usage requirements, and the materials are recyclable. For the purpose of protecting the environment, aluminum cans are widely used. From the pull ring, the lid to the jar body, they are all made of aluminum alloy.

Can lids can be made of 3104-h19 aluminum coil strip or 5052-H19 aluminum coil strip, which has good metallurgical quality, high dimensional accuracy, small thickness fluctuation, good punching and forming performance, excellent surface and mechanical properties, etc. Features, excellent quality, deeply welcomed by the market.

Can lid material 3104 and 5052 aluminum coils standards

• 1. Flatness: Aluminum coils and strips are not allowed to have obvious waves, the wave height does not exceed 3mm, and the waves do not exceed 3/meter.
• 2. Side curvature: The side curvature of the product at any length of 2000mm should not be greater than 0.5mm.
• 3. End warpage: For any product with a length of 1500mm, the height of end warpage is ≤5mm.
• 4. Joints: No joints are allowed.
• 5. Surface quality: Serious bubbles, missed coatings, scratches, corrosion, oil spots, peeling, stripes, color differences, petals, roller marks, periodicity, etc. that affect the appearance quality of the product are not allowed. Burrs are ≤0.04mm.
• 6. End face quality: The end face is neat, tightly rolled without loose layers, staggered layer ≤ 2mm, tower shape ≤ 5mm.

Both 3104 and 5052 aluminum coils need to meet relevant standard requirements in the manufacture of can lid materials. The choice of which material to use usually depends on the specific application requirements and manufacturing process.

In practical applications, aluminum coil manufacturers usually select appropriate aluminum alloy materials based on the specific requirements of can lid materials and production processes (aluminum coils often only provide suggestions to customers, and it mainly depends on the customer's choice).
