3004 Aluminum Alloy Coil 0.1-260mm Thickness for Packaging Applications with 130-285 MPa Tensile Strength

3004 aluminum alloy is a medium-strength, non-heat-treatable alloy composed of manganese and magnesium. It provides superior strength compared to pure aluminum while maintaining excellent formability, weldability, and corrosion resistance.

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 processes like rolling.

High ductility suitable for deep drawing, stretching, and other forming processes, making it ideal for beverage can bodies.

Resists atmospheric, water, and chemical corrosion due to manganese and magnesium content, particularly effective in humid and saline environments.

Compatible with conventional welding methods including MIG/TIG, making it perfect for sealed packaging containers.

Low density of approximately 2.7 g/cm³, significantly lighter than steel, reducing transportation costs.

Used for beer, soda cans, and food containers. 3004 sheets are deep-drawn into cylindrical can bodies, replacing 3003 alloy with higher strength due to magnesium content. Surfaces can be coated or printed for branding.

Stamped into screw caps, crown caps, and aerosol cans for cosmetics and pharmaceuticals, providing excellent sealing properties and pressure resistance.

Aluminum foil laminates combined with plastic films for snack bags and pharmaceutical blister packs. Also used for lightweight, recyclable trays and containers for takeout food boxes and industrial packaging.
