What are the aluminum bottle cap material grades for beverage caps?

Aluminum bottle caps are widely used in the beverage industry due to their lightweight, corrosion resistance,recyclability, and ability to maintain product freshness. Selecting the right material grade is crucial for ensuring safety, performance, and compatibility with different types of beverages, such as soft drinks, beer, or juices.

Common Aluminum Grades for Beverage Caps

1. Aluminum 3104 H19

Characteristics:High corrosion resistance, excellent formability, and good strength.

Applications: Widely used for crown caps (beer and carbonated drinks) due to its ability to withstand high-speed capping processes.

Benefits: Prevents leakage, maintains carbonation, and is cost-effective.

2. Aluminum 5182 H48

Applications: Often used in twist-off caps for beverages like juices or bottled water.

Characteristics: Stronger than 3104,moderate corrosion resistance, good springback.

Benefits: Offers better mechanical strength for reusable or resealable caps.

3. Aluminum 8011 H18 / H19

Characteristics:Excellent corrosion resistance, very good formability, and safe for food contact.

Applications:Common in food and beverage lids, including soft drink and beer caps.
