Aluminum coil for beverage can tab stock is a specialized aluminum material used to manufacture the end parts of beverage cans, including aluminum bottles and other containers. These aluminum coils are known for their excellent mechanical properties, corrosion resistance, and good processability, fully meeting the requirements for sealing, storage, and transportation of beverages. GNEE aluminum beverage can tab stock coils are widely used in the sealing sections of carbonated drink cans, fruit juice cans, beer cans, and other beverages, ensuring both corrosion resistance and airtightness while enhancing the overall quality and appearance of the cans.
Common Aluminum Alloys for Beverage Can Tab Stock
The most commonly used alloys for beverage can tab stock are 5052 and 5182, chosen for their superior mechanical properties, corrosion resistance, and workability.
1. 5052 Aluminum Coil
Composition: Primarily aluminum and magnesium, with magnesium content of 2.2%–2.8%.
Performance Characteristics:
Excellent corrosion resistance, including resistance to seawater and chemical media.
Medium strength, with adequate tensile and yield strength for end-use applications.
Good formability, suitable for stamping, bending, and welding.
Applications: Widely used for the top and bottom ends of beverage cans and aluminum bottles.
2. 5182 Aluminum Coil
Composition: Mainly aluminum and magnesium (4.0%–4.9%), with small amounts of manganese and chromium.
Performance Characteristics:
High strength, suitable for components under higher stress.
Excellent corrosion resistance, ideal for beverage can environments.
Good machinability, capable of forming complex shapes.
Applications: Often used for can ends requiring higher strength and pressure resistance.
Performance Requirements for Beverage Can Tab Stock:
Sealability: Ensures airtight sealing to maintain beverage freshness.
Pressure Resistance: Capable of withstanding internal pressures, especially in carbonated drinks.
Corrosion Resistance: Resists corrosion from beverage contents to maintain material stability.
Machinability: Easy to stamp, form, and weld.
Lightweight: Reduces the overall weight of cans for easier transport and storage.
Recyclability: Meets environmental standards through aluminum recycling.
Both 5052 and 5182 aluminum alloys are excellent options for beverage can tab stock, providing reliable performance for sealing beer, soft drinks, fruit juices, and other canned beverages.
