EN573 3000 Grade 3004 Aluminium Alloy EN AW 3004 Aluminum Coil Supplier
Aluminum 3004 is a medium strength aluminum alloy with manganese and magnesium as
its primary alloying elements. It has higher strength than 3003 alloy but lower ductility.
Mechanical Properties
• Tensile Strength: 180-240 MPa (H34 temper)
• Elongation: 8-15% (H34 temper)
• Hardness: 60-80 HB (H34 temper)
Physical Characteristics
• Density: 2.72 g/cm³
• Thermal Conductivity: 163 W/(m·K)
• Electrical Conductivity: 40% IACS
Competitive Advantages
① Enhanced Strength-Formability Balance
30% stronger than 3003 alloy
Maintains ≥10% elongation (H34 temper)
② Superior Corrosion Resistance
Excellent SCC resistance (outperforms 5052)
Withstands carbonated beverage corrosion for 18+ months
③ Optimized Deep Drawing Performance
Earing rate <3% (better than 3003)
Plastic strain ratio (r-value): 0.85
④ Cost Efficiency
15-20% cost savings vs 5182 alloy
Recycling rate >95%
Common Applications
① Packaging:
Can bodies: 3004-H19 (0.255mm±0.005mm)
Can ends: 5182-H48 (thinner/harder)
② Transportation:
EV battery enclosures (1.2-2.0mm)
Truck body panels (2.5mm corrugated)
③ Construction:
Standing seam roofing (1.0mm)
Composite panel cores (0.8mm foil)
