Aluminum alloy bottle caps are usually made of a variety of different types of aluminum alloy materials, mainly 1 series, 3 series, 5 series and 8 series aluminum alloys. These materials have their own unique properties and characteristics. They have good strength, corrosion resistance, ductility and plasticity, and are suitable for manufacturing bottle caps, which need to undergo multiple mechanical processing (such as stamping, stretching, rolling).

Introduction to common aluminum alloys:

1 series aluminum alloy (such as 1050, 1060)

Features: pure aluminum, high aluminum content (≥99%), strong ductility, excellent corrosion resistance.

Application: used for lightweight, decorative bottle caps or products with low strength requirements.

3 series aluminum alloy (such as 3104, 3105)

Features: aluminum-manganese alloy, with good corrosion resistance, medium strength and excellent processing performance.

Application: The most common choice, used for food, beverage bottle caps (such as beer bottle caps, carbonated beverage bottle caps) and medical bottle caps.

5 series aluminum alloy (such as 5052, 5182)

Features: Aluminum-magnesium alloy, with high strength, excellent corrosion resistance and good sealing performance.

Application: Used for high-end beverage bottle caps or medical bottle caps with high sealing requirements, especially suitable for high humidity environments.

8 series aluminum alloy (such as 8011)

Features: Aluminum-iron-silicon alloy, economical and practical, good ductility and moderate strength.

Application: Suitable for ordinary bottle caps and food sealing packaging.

Performance characteristics of aluminum alloy bottle cap materials:

1. Lightweight: low density, reducing transportation weight and transportation costs.

2. Corrosion resistance: excellent performance, suitable for food and beverage packaging, can be stored for a long time.

3. Environmental protection: easy to recycle and reuse, reduce waste and save resources.

4. Aesthetics: strong plasticity, beautiful shape and surface treatment, enhance brand image.

5. Sealing: good sealing performance, prevent microorganisms and oxygen intrusion, and extend shelf life.

6. Functionality: anti-counterfeiting function, help identify counterfeit goods.

7. Economic efficiency: low production cost, high overall cost-effectiveness, reduce transportation and storage losses.
