Aluminum Foil

Product SKU: AL-3003-FOIL
Alloy Grade: 3003 H14/H18/H24/H26 (Custom Temper on Request)
Core Advantage: Superior corrosion resistance, enhanced strength, excellent weldability & versatile formability

Product Overview

3003 aluminum foil is a heat-treatable wrought alloy composed of 98.6% minimum aluminum, alloyed with manganese (1.0-1.5%) to deliver exceptional mechanical strength and corrosion resistance—outperforming pure aluminum foils in harsh environments. As a widely trusted grade in industrial and commercial sectors, it balances ductility with structural integrity, making it suitable for complex forming, welding, and laminating processes. Our 3003 foil is manufactured via precision cold-rolling and annealing technologies, ensuring consistent thickness, smooth surface finish, and minimal pinhole defects, fully compliant with international industrial standards (ASTM B479, EN 573-3).

Key Specifications

Core Performance Features

- Exceptional Corrosion Resistance: Manganese alloying provides superior resistance to atmospheric corrosion, saltwater exposure, and mild chemical solutions (acids, alkalis), making it ideal for outdoor and harsh-environment applications.
- Enhanced Mechanical Strength: Tensile strength ranges from 120MPa (O temper) to 240MPa (H26 temper), offering higher load-bearing capacity than pure aluminum foils while maintaining good ductility for bending and forming.
- Excellent Weldability & Bonding: Compatible with various welding methods (TIG, MIG, resistance welding) and adheres well to adhesives, plastics, and papers—suitable for composite material production and structural assemblies.
- Thermal & Electrical Conductivity: Thermal conductivity of 201 W/(m·K) and electrical conductivity of 38% IACS, enabling efficient heat transfer and electromagnetic shielding applications.
- Uniform & Defect-Free Surface: Precision rolling ensures thickness tolerance of ±0.8μm (for foils <50μm) and ±1.0μm (for foils >50μm), with no pinholes (≤3 pinholes/m² for 8-20μm foil) and smooth edges for safe processing.

Typical Applications

1. Industrial Manufacturing: Heat exchangers, HVAC insulation, cable shielding, battery casings, chemical storage liners, and automotive heat shields.
2. Packaging & Containers: Chemical drum liners, pharmaceutical blister packaging (for moisture-sensitive drugs), industrial component packaging (rust prevention), and flexible intermediate bulk containers (FIBCs).
3. Construction & Architecture: Vapor barriers, roof underlayment, sound insulation materials, and decorative laminates.
4. Food & Beverage (Specialized): High-temperature sterilization packaging, retort pouches, and food processing equipment liners (FDA-compliant grades available).
5. Electronics & Electrical: Capacitor foils, electromagnetic interference (EMI) shielding, and printed circuit board (PCB) substrates.
