Al-Mg-Mn Alloy 3004 Aluminum Siding Coil For Curtain Wall
3004 series alloy (Al-Mn-Mg system) that undergoes surface cleaning, chemical pretreatment,
and coating application (typically with high-performance PVDF fluorocarbon or polyester paints)
followed by high-temperature curing.
Primarily used for:
-
Curtain walls (weather-resistant, UV-proof)
-
Roofing systems (lightweight, corrosion-resistant)
-
Architectural decoration (versatile colors/finishes, easy fabrication)
Key Characteristics of 3004 Aluminum Coil
3004 is an Al-Mn-Mg series alloy (typically supplied in H34/H44 tempers) that, when color-coated,
exhibits:
Mechanical Properties
Tensile strength: 180-240 MPa (H34 temper reaches ≥240 MPa)
Elongation: ≥8% (H34), excellent for stamping and forming
Corrosion Resistance
Mn and Mg elements enhance atmospheric/rain corrosion resistance
Formability
Excellent bendability and deep-drawing capability for complex facade shapes
2 kinds export forms
coil and sheet , we can produce 1800mm ultra-wide at most for the coil.
Performance Advantages for Curtain Walls
Lightweight
Density: 2.7g/cm³ (65% lighter than steel), reducing structural loads
Aesthetic Flexibility
Custom PVDF colors (metallic, woodgrain effects) with UV resistance (ΔE<3 after 15 years)
Weather Resistance
Stable performance across -40℃ to 80℃ with no cracking/deformation
Cost Efficiency
Lower lifecycle cost vs stainless steel/zinc; minimal maintenance (cleaning only)
Notable Project Applications
✅ Skyscrapers: Shanghai World Financial Center (decorative elements)
✅ Airports: Beijing Daxing Airport (curved sunshades)
✅ Commercial Complexes: Parametric facade systems
