3003 Aluminum Foil Jumbo Rolls
3003 aluminum foil is an aluminum alloy renowned for its versatility, durability, and excellent corrosion resistance. It is one of the most commonly used alloys in the aluminum foil industry, offering a balance of strength, flexibility, and performance across a wide range of applications. It is stronger and more corrosion-resistant than pure aluminum (such as 1100 series aluminum) while maintaining excellent formability, making it a widely used mid-range industrial material. It provides a viable material solution for a variety of applications where special strength or extreme tolerance is not required.

Features of 3003 Aluminum Foil
- Enhanced Corrosion Resistance
Approximately 40% higher corrosion resistance than conventional pure aluminum foil, suitable for humid and mildly corrosive environments.
- Excellent Formability
High elongation enables rolling down to 0.01 mm thickness, ideal for deep drawing and complex forming applications.
- Superior Surface Quality
Surface roughness up to Ra ≤ 0.2 μm, ensuring a smooth finish for precision applications.
- Balanced Mechanical Properties
- O Temper: Soft with high ductility (elongation up to 20–30%), suitable for deep processing
- H/T Tempers: Higher strength while maintaining good formability
- Lightweight & Recyclable
Low density helps reduce overall product weight while supporting sustainability through recyclability.
- Reliable Barrier & Thermal Conductivity
Provides basic physical barrier performance, effectively blocking water vapor and reducing gas permeability; the metallic surface also enables efficient heat transfer and uniform thermal distribution.
- Stable Chemical Performance
Exhibits good chemical stability under normal conditions. The natural oxide layer enhances resistance to environmental corrosion, ensuring stable performance during storage and use in non-extreme environments.

Common Applications of 3003 Aluminum Foil
- Packaging Field
In packaging applications, 3003 aluminum foil is widely favored due to its lightweight characteristics and excellent barrier performance. Its dense metallic structure effectively blocks moisture, gases, and external contaminants, thereby extending the shelf life of food and other products. At the same time, it offers high portability and ease of use. It is particularly suitable for liquid and gas packaging, significantly reducing permeability risks and ensuring sealing integrity and package stability.
- Construction Field
3003 aluminum foil also plays an important role in the construction industry. Its good formability and processing performance allow it to meet diverse architectural design requirements and make it widely used in thermal insulation systems. As an insulating layer in energy-efficient doors, windows, or wall structures, aluminum foil effectively reflects thermal radiation and reduces heat transfer, thereby lowering building energy consumption. This contributes to energy savings, emission reduction goals, and reduced operating costs for users.
- Transportation Field
With the increasing demand for lightweight, safety, and durability in the automotive industry, 3003 aluminum foil is being used more widely in transportation applications. Its excellent corrosion resistance and barrier properties make it suitable for fuel systems, thermal insulation materials, and structural support components. It helps reduce overall vehicle weight, improve safety performance, and extend service life.
- Aerospace Field
Aerospace applications impose extremely stringent requirements on material performance. Thanks to its lightweight nature, high stability, and strong environmental adaptability, 3003 aluminum foil maintains reliable performance under complex conditions such as high and low temperatures and corrosive environments. In addition, its good strength and toughness contribute to enhancing the overall reliability and safety of aerospace equipment.
