Alloy Material Selection Guide
| Alloy | Temper | Tensile Strength | Key Feature | Typical Use |
| 3003 | H14/H24 | 145-185 MPa | Cost-effective | Basic cladding |
| 3004 | H34 | 200-240 MPa | High wind-load resistance | Coastal areas |
| 5052 | H32 | 230-280 MPa | Excellent corrosion resistance | Industrial zones |
Key Advantages
✓ Lightweight & High Strength - Density: 2.7g/cm³ (1/3 of steel), reducing structural load. 5052-H32: Tensile strength ≥230MPa; 6061-T6: Up to 310MPa
✓ Superior Weather Resistance - Natural oxide layer resists UV; Anodizing triples durability. 5,000-hour salt spray test (GB/T 10125 compliant)
✓ Design Flexibility - Roll-forming, bending, stamping (min. bend radius = thickness). Supports parametric curved designs (e.g., double-curvature walls)
Diverse Surface Finishes
| Finish | Features | Applications |
| PVDF Coating | 20-year color retention | Landmarks (e.g., Shanghai Tower) |
| Anodizing | Metallic finish, hardness ≥300HV | Premium office buildings |
| Wood Grain | Natural texture, -40~80℃ range | Cultural/retail projects |
✓ Energy Efficiency - Solar reflectance ≥80% (reduces cooling costs). 100% recyclable; recycled aluminum uses 95% less energy
