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)
