3000 Grade Alloy 3004 Aluminium Alloy Coil Price 3004 Coil Aluminum For Packages

3004 aluminum alloy is a medium-strength, non-heat-treatable alloy primarily composed of

manganese and magnesium. It offers better strength than pure aluminum while maintaining

good formability,weldability, and corrosion resistance.

key properties

♦ Moderate Strength

Tensile strength: 130–285 MPa (depending on temper, with H18 full-hard state offering the highest

strength). Strength can be significantly improved through cold working (e.g., rolling), but it cannot

be heat-treated for strengthening.

♦ Excellent Formability

High ductility, suitable for deep drawing, stretching, and other forming processes (e.g., beverage can bodies).

♦ Outstanding Corrosion Resistance

Due to its manganese (Mn) and magnesium (Mg) content, it resists atmospheric, water, and chemical

corrosion, particularly in humid and saline environments.

♦ Good Weldability

Compatible with conventional welding methods (e.g., MIG/TIG), making it ideal for sealed packaging

containers.

♦ Lightweight

Low density (~2.7 g/cm³), lighter than steel, reducing transportation costs.

Mechanical Properties

Applications in the Packaging Industry

3004 aluminum alloy is widely used in packaging due to its corrosion resistance, formability, and food

safety compliance. Key applications include:

1. Beverage and Food Can Bodies

Beverage Can Bodies (e.g., Beer, Soda Cans)

3004 sheets are deep-drawn into cylindrical can bodies, replacing 3003 alloy (3004 offers higher

strength due to Mg content). Surfaces can be coated or printed for branding.

Food Cans: Used for meat, vegetables, etc., offering corrosion resistance and non-toxicity.

2. Bottle Caps and Seals

Screw Caps, Crown Caps:

Stamped into lids with excellent sealing properties (e.g., water bottle caps, wine caps).

Aerosol Cans (Spray Cans):

Used in cosmetics and pharmaceuticals, requiring contamination-free and pressure-resistant materials.

3. Other Packaging Containers

Aluminum Foil Laminates: Combined with plastic films for snack bags, pharmaceutical blister packs, etc.

Trays and Containers: Lightweight and recyclable, suitable for takeout food boxes or industrial packaging.
