About Aluminum Alloys and Weight Calculation in Construction
Aluminum alloys are widely used in construction due to their low density, corrosion resistance, and versatility. The calculator uses precise alloy densities to help you estimate the material's weight contribution to a building's dead load.
Aluminum Alloy Series and Construction Uses
- 1000 Series: Pure Aluminum (~2.71 g/cm³). Used for cladding, flashing, or electrical applications.
- 2000 Series: Al-Cu (~2.78–2.80 g/cm³). Higher strength for structural components like beams or brackets.
- 3000 Series: Al-Mn (~2.73 g/cm³). Ideal for roofing and siding in houses and industrial buildings.
- 4000 Series: Al-Si (~2.68–2.69 g/cm³). Used primarily for welding or casting in fittings.
- 5000 Series: Al-Mg (~2.66–2.70 g/cm³). Excellent corrosion resistance for marine/coastal siding or panels.
- 6000 Series: Al-Mg-Si (~2.70 g/cm³). Most common for construction: window frames (6063), structural beams (6061).
- 7000 Series: Al-Zn (~2.78–2.83 g/cm³). Highest strength for heavy-duty structural applications in large buildings.
- 8000 Series: Special (e.g., 8090, 2.55 g/cm³). Used for foil/flashing or specialized lightweight panels.
Weight Calculation Notes
This calculator uses specific volume formulas for common shapes. For highly accurate results with complex profiles, select the **'Custom Extrusion'** shape and manually enter the cross-sectional area (A) as provided by your manufacturer or CAD data. Tube calculations are approximations (assuming a 20% wall thickness ratio).
| Component | Typical Alloy | Typical Thickness | Example Weight |
|---|---|---|---|
| Window Frame | 6063 | 1.2–2 mm wall | 10–20 kg/window |
| Siding (1,000 sq ft) | 5052/3103 | 0.5–0.7 mm | 125–175 kg |
| Curtain Panel | 6063 | 1.5–3 mm | 15–25 kg/m² |
