What is 3003 Aluminium Alloy Foil?
3003 aluminium alloy foil is a manganese-enriched variant of commercial-grade aluminum, known for its balanced strength, formability, and corrosion resistance. With 1.2% manganese content, it outperforms 1100 aluminum in durability while retaining excellent workability. This foil is widely used in packaging, heat exchangers, and construction due to its cost-effectiveness and adaptability.

3003 Aluminium Alloy Foil Specifications
- Alloy Composition: 98.4% aluminum, 1.2% manganese, trace iron
- Temper Options: H14, H16, H18, H22 (affects hardness)
- Thickness Range: 0.006mm–0.2mm
- Standards: ASTM B209, GB/T 3880.1
This alloy’s enhanced tensile strength (150–250 MPa) makes it ideal for moderate-stress applications like bottle stoppers and flexible ducting.
Key Properties That Define 3003 Aluminium Foil
- Corrosion Resistance: Oxidation-resistant in humid/wet environments
- Formability: Easy to bend, fold, or emboss
- Thermal Conductivity: Efficient heat distribution (205 W/m·K)
- Non-Magnetic & Non-Toxic: Safe for food packaging
Unlike 5052 aluminum (used in marine settings), 3003 aluminum foil lacks saltwater resistance but excels in cost-efficient, indoor applications.
Manufacturing Process of 3003 Aluminum Foil
Production involves:
- Melting: Aluminum ingots mixed with manganese.
- Rolling: Hot-rolled into sheets, then cold-rolled to thin gauges.
- Annealing: Softens metal for flexibility.
- Cutting: Precision slitting to customer specifications.
This process ensures consistent thickness and zero defects, critical for industries like pharmaceuticals requiring sterile packaging.
Benefits of Choosing 3003 Aluminum Alloy Foil
Cost-Effective: Lower price than high-alloy foils
Easy to Print: Matte finish accepts ink well
Eco-Friendly: 100% recyclable
Durable: Resists tearing and fatigue
Businesses saving on materials without sacrificing performance often opt for 3003 aluminum foil over premium grades.
