3003 Aluminum Sheet

3003 aluminum sheet is a manganese-containing aluminum alloy sheet known for its good mechanical properties and corrosion resistance. Compared with pure aluminum sheet, it has improved strength while maintaining good formability and weldability. This sheet is suitable for applications that require moderate strength and chemical corrosion resistance, such as roofing, curtain walls, interior materials in the construction industry, as well as the manufacture of transportation vehicles, household appliances, storage tanks and general engineering structures. 3003 aluminum sheet is easy to process, whether it is cutting, stamping or bending, it can meet the needs of complex designs. Its wide range of applications and economy make it the preferred material in many industries.

3003 aluminum sheet provides standard specifications of 0.3-150mm thickness and 800-2500mm width, and the length can be customized to 12000mm. Made of aluminum-manganese alloy (Mn content 1.0-1.5%), it complies with ASTM B209/EN485 standards, with a thickness tolerance of ±0.02mm and a flatness of ≤1I-unit. Special specifications can be customized, with the maximum single plate size up to 3000×12000mm and a weight of 8 tons. The surface finish is Ra0.8μm, suitable for high-precision sheet metal processing, and provides a variety of state options such as O, H12, H14, H16, and H18.

1. Construction industry: used to make roof panels, gutters, downpipes and curtain wall materials.

2. Transportation industry: manufacturing body panels for trucks and trailers, as well as some aircraft parts.

3. Packaging industry: as raw material for food and beverage cans.

4. Air conditioning and refrigeration: used to make pipes and components for air conditioning systems.

5. General engineering: making ladders, scaffolding, containers and various mechanical parts.

6. Household appliances: the outer shell or internal components of some refrigerators, washing machines and other household appliances.

7. Chemical and food processing: due to its good corrosion resistance, it is suitable for storage tanks and piping systems in these industries.
