Features of 3004 Aluminum Foil

01. Core Material Properties

3004 aluminum foil uses aluminum as the base metal with manganese and magnesium added to enhance its mechanical and chemical performance.

• Manganese content of 1.0%–1.5% improves work-hardening capability and corrosion resistance.
• Magnesium content of 0.8%–1.3% enhances tensile strength and structural stability.
• Tensile strength reaches 150–285 MPa, approximately 30% higher than 3003 alloy.
• Density of approximately 2.72 g/cm³ provides significant lightweight advantages.
• Thermal conductivity of about 148 W/(m·K) ensures excellent heat transfer performance.

02. Excellent Physical and Processing Performance

3004 aluminum foil combines flexibility with structural strength.

• Excellent ductility suitable for deep drawing, bending, and complex forming processes.
• Resistant to cracking and wrinkling during deep drawing.
• Can withstand more than 20 folding cycles without breaking.
• Thickness can be reduced to as low as 0.006 mm while maintaining complete barrier performance.
• Available in multiple tempers such as O, H12, and H14 to meet various processing requirements.

03. Outstanding Barrier and Corrosion Resistance

3004 aluminum foil provides excellent moisture resistance, oxidation resistance, and environmental durability.

• Highly effective barrier against moisture and oxygen.
• Water vapor barrier rate exceeds 99% at 0.03 mm thickness.
• Resistant to liquid environments with pH values ranging from 2 to 11.
• Naturally forms a dense oxide layer that protects against further corrosion.
• Maintains stability in humid, salt spray, and outdoor environments.

04. Stable Temperature Resistance

3004 aluminum foil maintains reliable performance across a wide temperature range.

• Operating temperature range from approximately -40°C to 150°C.
• Suitable for frozen food, heating, and heat-sealing applications.
• Excellent thermal conductivity for heat dissipation and heat exchange systems.
• Surface treatments such as anodizing and PVDF coating can further improve weather resistance and UV resistance.

Manufacturing Process

3004 aluminum foil is typically produced through melting, continuous casting and rolling, cold rolling, foil rolling, and annealing processes.

• Melting temperature controlled at 740–750°C.
• Intermediate annealing temperature around 380°C to optimize grain structure.
• Multi-pass precision rolling ensures tight thickness tolerances.
• Corona treatment can increase surface tension to above 38 dyn/cm.
