3104 H19 Aluminum Sheet for Easy Pull-Tab Can Lids

3104 H19 aluminum sheet is a type of aluminum alloy material specifically designed for the production of easy-pull can lids. It is widely used for the lids of beverage and food cans. Its unique alloy composition and excellent processing performance make it an ideal choice for manufacturing easy-pull can lids and pull-tabs, meeting various requirements such as high strength, excellent formability, and corrosion resistance.

3104 H19 Aluminum Sheet Properties

Moderate Strength

The 3104 H19 aluminum sheet provides sufficient strength for the can lids while maintaining enough ductility to prevent cracking during opening. Its excellent impact resistance allows the lid to withstand pressure from the pull-tab and fingers during opening, while maintaining the integrity of the lid.

Good Corrosion Resistance

Due to the inherent properties of aluminum alloy, 3104 H19 aluminum sheet has excellent corrosion resistance, especially suitable for contact with various beverages (such as acidic or alkaline drinks). This ensures that during long-term storage of food and beverages, the material will not react with the contents, preserving its quality and safety.

Excellent Formability

This aluminum sheet has outstanding formability, capable of undergoing complex stamping and stretching processes, easily producing easy-pull can lids that meet various design requirements. Its surface is smooth and uniform, contributing to the final product's aesthetics and quality.

Appropriate Elongation

The 3104 H19 aluminum sheet has an appropriate elongation rate, making it resistant to cracking during the stamping process. It effectively meets the production needs of easy-pull can lids and pull-tabs, ensuring efficiency and stability during manufacturing.

3104 H19 Aluminum Sheet for Easy Pull-Tab Can Lids Applications

The application of 3104 H19 aluminum sheet is mainly focused on the lids of easy-pull cans, particularly for beverage and food cans.

Beverage Can Lids

This aluminum sheet is highly suitable for use as the easy-pull lid of beverage cans (such as carbonated drinks, juices, etc.) due to its excellent formability, corrosion resistance, and moderate strength. These lids effectively preserve the freshness and safety of the beverages, preventing leakage or contamination.

Food Can Lids

Similar to beverage can lids, 3104 H19 aluminum sheet is also commonly used for sealing food cans, such as canned goods and soups. Its corrosion resistance and high strength ensure long-term storage and easy opening of the food products.

Pull-Tabs

Although pull-tabs for beverage cans are primarily made from 5182 aluminum sheet, the excellent formability of 3104 aluminum sheet also allows it to be used for manufacturing pull-tabs in some cases, particularly for cost control or special requirements.

3104 H19 Aluminum Sheet for Easy Pull-Tab Can Lids Manufacturing Process

The 3104 H19 aluminum sheet is meticulously manufactured and treated, typically using stamping and stretching processes for forming. Due to its outstanding ductility and toughness, these aluminum sheets can be processed into complex shapes to meet the design requirements of easy-pull can lids. The aluminum sheet is also surface-treated to ensure a smooth and flawless final product.
