Inputs
MetricDensity auto-fills by alloy and units.
| Alloy | Typical Density (kg/m³) | Notes |
|---|---|---|
| 1100 | 2710 | Commercially pure, excellent corrosion resistance. |
| 2024 | 2780 | High strength, aircraft grade. |
| 3003 | 2730 | Manganese alloy, good formability. |
| 5052 | 2680 | Marine grade, very good corrosion resistance. |
| 5083 | 2650 | Shipbuilding, high magnesium content. |
| 6061 | 2700 | General purpose structural alloy. |
| 6063 | 2700 | Extrusion-friendly, architectural. |
| 6082 | 2700 | Similar to 6061, higher manganese. |
| 7050 | 2810 | High strength, aerospace. |
| 7075 | 2810 | Very high strength, aerospace. |
Imperial density will be auto-converted to lb/in³ when selected.

Formula Used
General: Weight = Volume × Density.
- Rectangular (sheet/flat): V = L × W × T.
- Round bar: V = L × π × D² / 4.
- Round tube: V = L × π × (Do² − Di²) / 4, with Di=Do−2t if not given.
- Square tube: V = L × (B² − (B − 2t)²).
- Angle (L): Cross-section area A = t × (A + B − t); V = A × L.
Units: Metric uses mm for diameters/thickness/legs and m for length; Imperial uses inches for diameters/thickness/legs and feet for length. The calculator converts to consistent base units internally.

FAQs
Generic aluminium ≈ 2700 kg/m³. 1100 ~ 2710, 2024 ~ 2780, 3003 ~ 2730, 5052 ~ 2680, 5083 ~ 2650, 6061/6063/6082 ~ 2700, 7050/7075 ~ 2810. Override with mill data as needed.
This tool assumes idealized shapes. Corner radii, chamfers, and weld seams are ignored. For critical jobs, apply a contingency or model actual profiles for accuracy.
Yes. Unit labels update instantly. Previously added rows retain their numeric values but display with the current unit symbols and recalculated density basis.
Results are geometric idealizations using the selected density. Actual delivered weight varies with tolerances, temper, and chemical composition. Adjust decimals to suit reporting needs.
In Metric, length input is meters; other dimensions are millimeters. In Imperial, length input is feet; other dimensions are inches. The tool converts internally before computing volume.
