3003 aluminum sheet belongs to the 3000 series Al-Mn alloy family and is one of the most widely used aluminum alloys for industrial applications. Compared with 1100 aluminum, it provides approximately 20% higher strength while maintaining excellent corrosion resistance and formability.
The alloy performs well in bending, roll forming, deep drawing, and welding operations, making it suitable for architectural components, insulation systems, roofing materials, chemical equipment, and general fabrication projects where durability and workability are important.
The 3003 aluminum sheet is one of the most widely specified rust-proof Al-Mn aluminum alloy plates in modern manufacturing and construction. Formulated with manganese as its primary alloying addition, 3003 aluminum provides approximately 20% higher mechanical strength than 1100 series pure aluminum while maintaining exceptional ductility, workability, and surface polishability.
Compared to heat-treatable structural alloys, 3003 aluminum sheet offers outstanding atmospheric corrosion resistance, superior weldability via conventional TIG and MIG welding, and superior deep-drawing capability. It performs reliably during severe bending, roll-forming, stamping, and cutting operations without developing edge cracks or structural defects, making it an ideal choice for decorative cladding, roofing systems, and chemical processing equipment.
For international sheet fabricators, insulation contractors, and wholesale metal stockists, our manufacturing facility ensures precise gauge tolerances, smooth flat surfaces, and competitive factory-direct pricing for high-volume orders. All raw metal sheet plates strictly adhere to recognized global quality standards such as ASTM B209 specifications.
These versatile anti-rust metal sheet plates are extensively specified across architectural design, HVAC insulation, automotive fabrication, and food packaging sectors. Typical applications include:
We supply 3003 aluminum sheet products in a full range of standard sheet sizes (such as 4×8 ft, 1220×2440 mm, 1500×3000 mm), custom cut-to-length plate sizes, tempers (such as Soft Annealed O, H14, H18, H24), and protective edge configurations.
Available value-added processing services include precision CNC laser cutting, waterjet shearing, custom press bending, surface embossing, satin brushing, color prepainting, paper interleaving, and heavy-duty PE/PVC protective laser film application to guard against scratching during export transit.
Our experienced export logistics team guarantees short lead times, seaworthy wooden pallet packaging with waterproof protective wrapping, and authentic Mill Test Certificates (MTC) accompanying every shipment for complete material traceability.
