3003 aluminum foil is a popular material in various industries, prized for its unique combination of strength, corrosion resistance, and formability. As a member of the 3XXX series aluminum alloys (aluminum-manganese), it stands out for its versatility—making it a go-to choice for both industrial and commercial applications. Below, we’ll explore its key properties, alloy composition, mechanical performance, and primary uses.
3003 aluminum is an aluminum-manganese alloy, with a chemical makeup that balances durability and workability. Its typical composition (per industry standards like GB/T3880-2012) includes:
Alloy | Si | Fe | Cu | Mn | Mg | Zn | Ti | V | Others | Al |
3003 | 0.6 | 0.7 | 0.05-0.2 | 1.0-1.5 | 0.1 | 0.2 | Remain |
This composition gives 3003 aluminum foil better strength than pure aluminum (1XXX series) while retaining excellent ductility—critical for processes like rolling, folding, and shaping.
Alloy | Temper | Thickness | Tensile Strength (Rm/Mpa) | Elongation (Not Less Than) |
3003 | O | 0.018 - 0.2 | 80 - 140 | - |
3003 | H22 | 0.02 - 0.05 | 90 - 130 | 10 |
3003 | H22 | 0.05 - 0.2 | 90 - 130 | 10 |
3003 | H14 | 0.03 - 0.2 | 140 - 170 | - |
3003 | H24 | 0.03 - 0.2 | 140 - 170 | 1 |
3003 | H16 | 0.1 - 0.2 | ≥180 | - |
3003 | H26 | 0.1 - 0.2 | ≥180 | 1 |
3003 | H18 | 0.01 - 0.2 | ≥190 | 1 |
3003 | H19 | 0.018 - 0.1 | ≥200 | - |
3003 aluminum foil is widely used across industries:
Used for wrapping foods, snacks, and ready-to-eat meals. Its corrosion resistance prevents interaction with acidic or salty foods, while its barrier properties lock in freshness.
Formed into lids for cans, jars, and takeout containers, providing a tight seal to prevent spoilage.
Used in automotive and HVAC systems. Its thermal conductivity (≈190 W/m·K) and corrosion resistance make it ideal for transferring heat efficiently.
Thin 3003 foil wraps around wires and cables to block electromagnetic interference (EMI) in electronics.
Laminated to insulation materials in HVAC ducts to reflect heat and resist moisture, improving energy efficiency.
Printed or coated 3003 foil is used in interior design for wall accents, furniture, and signage, thanks to its smooth surface and paintability.
Shaped into heat-resistant gaskets for engines and fuel systems, leveraging its strength and resistance to oils.
Layered in car doors and floors to reduce noise, as its malleability allows it to conform to tight spaces.
Used for packaging pills and tablets. Its resistance to mild chemicals ensures compatibility with medications, while its formability creates secure, tamper-evident blisters.
