3003 Aluminum Plate and Sheet
3003 aluminum sheet belongs to the aluminum-manganese alloy series and is a common non-heat-treatable alloy. Due to its excellent anti-rust properties, it is also known as a rust-proof aluminum sheet. This characteristic mainly stems from its manganese alloy content (approximately 1.0–1.5%). Compared with pure aluminum (such as 1100 aluminum alloy), the strength of 3003 aluminum sheet is about 20% higher, while maintaining good formability and corrosion resistance.
3003 aluminum sheet is a cost-effective and widely used aluminum alloy product. It performs excellently in decorative, structural, and anti-rust applications, making it an indispensable basic material in both industrial and civil fields.
3003 aluminum sheet is one of the commonly used alloys in the 3000 series aluminum alloys, known for its good corrosion resistance, moderate strength, and ease of processing.
3003 aluminum alloy is a medium-strength alloy in the 3XXX series. Compared with the 1100 series, this composition increases its strength by about 20% while maintaining excellent formability and corrosion resistance. 3003 aluminum alloy is not heat-treatable and needs to be strengthened through cold working.
Common 3003 Aluminum Plate Metal Temper
- O
- H14
- H24
- H18
- H14, H16, H18: These tempers offer different levels of hardness, typically used in applications requiring moderate strength.
- O (Annealed): This soft temper is used for forming operations because it offers the highest workability.
3003 Aluminum Sheet Features
| Characteristic Category | Description |
| Anti-Rust Performance | 3003 aluminum sheet has extremely outstanding anti-rust performance, especially suitable for humid or corrosive environments. Its aluminum-manganese alloy composition provides good oxidation resistance, enabling the material to maintain a rust-free surface for a long time even in air or liquids containing weak acids or alkaline media. It is therefore often used in kitchen equipment, roofing materials, and curtain wall decoration fields. |
| Corrosion Resistance | 3003 aluminum sheet exhibits excellent corrosion resistance, particularly prominent under outdoor exposure and marine climate conditions. It can withstand moisture, salt spray, and other corrosive media without the need for additional protective coatings, making it an ideal choice for manufacturing refrigeration equipment, transport containers, and coastal building materials. |
| Formability | Due to its relatively low strength, 3003 aluminum sheet has excellent formability and is suitable for forming processes such as drawing, bending, spinning, and deep drawing. It has very good ductility, and cold processing at low or room temperatures does not lead to cracking or brittleness. In addition, its good weldability and ductility make it easy to connect with other materials or fabricate into various complex structures. |
| Strength | The tensile strength of 3003 aluminum sheet generally ranges from 110 to 150 MPa, classifying it as a medium-strength aluminum alloy. While it is not suitable for high-load-bearing or critical structural applications, its strength is sufficient for uses such as roofing cladding, automotive interiors, billboards, and some medium-to-light structural supports, especially in scenarios requiring weight reduction. |
| Machinability | 3003 aluminum sheet has excellent machinability, allowing precise processing with various standard cutting tools without tool sticking or work hardening problems. Its machining characteristics are suitable for stamping, sawing, milling, and other conventional processes. Combined with its good weldability, it performs ideally in mechanical manufacturing, mold making, and sheet metal processing industries. |
| Weight | 3003 aluminum sheet shares the lightweight properties typical of most aluminum alloys, with a density of about 2.73 g/cm³. This makes it an ideal lightweight material, significantly reducing the overall weight of equipment or components without sacrificing structural integrity. It is widely used in transport vehicles, aviation equipment, and mobile structures. |
| Surface Treatment | The surface of 3003 aluminum sheet is naturally smooth and can be further treated to achieve better aesthetic effects. Its surface is easy to polish and adaptable to anodizing, electrophoresis coating, painting, and other surface treatments. These processes not only enhance its decorative appearance but also improve corrosion resistance, making it highly favored in applications with high visual requirements such as interior and exterior decorative panels, ceilings, and signage. |
| Processing Performance and Coating | 3003 aluminum sheet performs excellently in both hot and cold processing, adapting to various industrial processing conditions. It is compatible with multiple surface coatings, including organic coatings, protective films, and functional coatings, further enhancing the material's appearance, aesthetics, and functionality. This makes it an important material for packaging containers, decorative panels, and industrial components. |
| Weldability | 3003 aluminum sheet has good weldability and can be welded using common methods such as gas welding, resistance welding, and MIG or TIG welding. The welding process is stable, and the welds are of high quality. It is suitable for manufacturing piping systems, food processing equipment, and containers requiring airtightness and liquid-tightness. |
| Anodizing Properties | Although 3003 aluminum sheet may exhibit slight discoloration during the anodizing process, it still maintains good decorative effects overall. It adapts well to organic coatings and mechanical polishing treatments, making it widely used in applications requiring both corrosion protection and aesthetics, such as decorative panels and electronic device housings. Despite the availability of various welding methods, torch welding is still recommended for some fine welding applications. |
