Al-Mg-Mn Alloy 3004 Aluminium Coated Sheet For Building 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

  • Roofing systems

  • Architectural decoration


Key Characteristics of 3004 Aluminum Coil

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


Common Tempers


Temper Characteristics Typical Applications
H34 Half-hard, high strength, good formability Curtain wall panels, 3D cladding
H44 Enhanced corrosion resistance, moderate strength Coastal/high-humidity areas
O (Annealed) Soft, superior deep-drawing capability Special curved designs (less common)


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


Notable Project Applications



Skyscrapers: Shanghai World Financial Center (decorative elements)

Airports: Beijing Daxing Airport (curved sunshades)
