The aluminum alloy strip used for can pull ring and can lid is an aluminum material that has been processed by hot rolling, cold rolling, annealing and other processes. The surface is oxidized and coated. It is designed to meet the high requirements of can products for strength, formability and corrosion resistance. Usually 5182 aluminum alloy, 5052 aluminum alloy, 3004 aluminum alloy, etc. are used, with a thickness range of 0.20-0.30mm.

Common aluminum alloy models:

5182 aluminum alloy: It has good strength, elongation and deep drawing performance, and is the main alloy on can pull ring materials. It belongs to aluminum-magnesium alloy, with good compressive strength and corrosion resistance, good toughness and not easy to deform.

3004 aluminum alloy: It is often used in can bottom manufacturing and also has good processing performance and corrosion resistance.

5052 aluminum alloy: In addition to being used to manufacture all-aluminum cans, it is also widely used in can lids of tinplate cans and other packaging containers.

Mechanical properties of aluminum alloy strips:

Advantages of aluminum strips for pull rings and can lids:

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

2. Good processing performance: easy to process into pull rings and can lids of various shapes and sizes.

3. Corrosion resistance: an oxide film is formed on the surface to protect the product from environmental erosion.

4. Recyclability: good recyclability, reducing environmental pollution.

Requirements for pull ring aluminum alloy strips:

According to relevant industry standards and specifications, aluminum alloy strips for can pull rings and can lids need to meet the following requirements:

1. Flatness requirements:

The wave height within 1 meter shall not exceed 3mm.

The number of waves shall not exceed 3/meter.

The edge curvature of the 2000mm segment shall not exceed 0.5mm.

The bending height of the end of the 1500mm segment shall not exceed 5mm.

No seams are allowed.

2. Surface quality requirements:

There shall be no serious bubbles, missing coating, scratches, corrosion, oil spots, peeling, stripes, color difference, spots, roller marks and other defects.

Burr ≤ 0.04mm.

Perfect transverse trimming, tight rolling, no loose layer phenomenon.

Stacking defect ≤ 2mm, overlapping defect ≤ 5mm.
