Product Description

Al-Mg-Mn Alloy AA3004 Coloured Aluminium Sheet For Curved Curtain Wall

AA3004 series alloy demonstrates moderate-to-high mechanical strength with outstanding corrosion

resistance, particularly against atmospheric conditions. It performs exceptionally well in humid and

saline environments. The material offers excellent processing characteristics including cold-forming

capability, weldability, and surface treatment adaptability.

Primarily used for:

Curtain walls (weather-resistant, UV-proof)
Roofing systems (lightweight, corrosion-resistant)
Architectural decoration (versatile colors/finishes, easy fabrication)

Standard Specifications

Parameter	Specification	Notes
Thickness	1.5-3.0mm	Thinner (<1.5mm) may deform; thicker (>3.0mm) complicates complex shaping
Temper	H34/H44	H34 (half-hard): balances strength/formability; H44: better corrosion resistance
Surface Finish	PVDF fluorocarbon coating (2-coat system)	Must meet ASTM D7863 for 25+ year color retention
Elongation	≥10% (H34 temper)	Ensures crack-free cold bending for complex curves

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

Performance Advantages for Double-Curved Facades

♦ Formability

High ductility (Mn/Mg alloying) enables cold bending for radii ≥1.5m (requires specialized roll-forming

equipment).

♦ Lightweight & Cost-Effective

1/3 the weight of glass facades, reducing structural costs with 30% faster installation.

♦ 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)

Comparison with Other Curved Facade Materials

Material	Minimum Curve Radius	Weathering	Maintenance
3004 Aluminum	≥1.5m	Excellent (PVDF)	Low (self-cleaning)
Stainless Steel	≥3m	Outstanding	Moderate (smudging)

Notable Project Applications

✅ Skyscrapers: Shanghai World Financial Center (decorative elements)

✅ Airports: Beijing Daxing Airport (curved sunshades)

✅ Commercial Complexes: Parametric facade systems
