3003 Alloy Aluminum Sheet 1.5mm Thickness with Excellent Formability for Chemical Storage Tanks

Our 3003 Anti-Rust Aluminum Sheet is a manganese alloyed grade that delivers approximately 20% greater strength than 1100 pure aluminum while maintaining excellent corrosion resistance. At 1.5mm thickness, this versatile sheet combines superior formability with outstanding weldability, making it the top choice for chemical storage tanks, building roofing systems, and general sheet metal fabrication.

• Manganese Strengthened: 1.0-1.5% manganese alloying provides 20% higher strength than commercially pure 1100 aluminum without compromising corrosion resistance
• Excellent Corrosion Resistance: Outstanding performance in atmospheric, freshwater, and mild chemical environments, ideal for outdoor applications
• Superior Formability: Readily formed by bending, deep drawing, spinning, and roll forming operations
• Good Weldability: Easily welded using TIG, MIG, and resistance welding techniques with 4043 or 5356 filler wire
• Non Heat-Treatable Stability: Properties remain stable after welding with no need for post-weld heat treatment

• Chemical storage tanks
• Pressure vessels
• Building roofing and siding
• Cooking utensils
• Food processing equipment
• Heat exchanger fins
• Truck and trailer panels
• Signage
• General sheet metal fabrication

All sheets undergo chemical composition verification via OES, tensile testing to ASTM E8 standards, and surface quality inspection for pinholes and surface defects. Flatness tolerance maintained within 0.5% of length per EN 485-3. Full material traceability from melt to shipment.
