Metal Weight Calculator Guide: All Metals Compared
Different metals have dramatically different densities. Knowing the density of your material is the key to accurate weight calculations for any shape or project.
Metal Density Reference Table
| Metal | Density (kg/m³) | Density (g/cm³) | Notes |
|---|---|---|---|
| Aluminium | 2,700 | 2.70 | Light, corrosion-resistant |
| Titanium | 4,507 | 4.51 | Strong and light |
| Iron (cast) | 7,200 | 7.20 | Brittle, compressive |
| Steel (mild) | 7,850 | 7.85 | Most common structural |
| Copper | 8,960 | 8.96 | Electrical conductor |
| Brass | 8,530 | 8.53 | Copper-zinc alloy |
| Lead | 11,340 | 11.34 | Very heavy |
| Gold | 19,300 | 19.30 | Densest common metal |
Weight Formula
1 × 0.5 × 0.005 × 2,700 = 6.75 kg
2 × 0.05 × 0.01 × 8,960 = 8.96 kg
Frequently Asked Questions
How do I calculate metal weight from volume?
Weight = Volume × Density. Volume is calculated from the shape's dimensions (e.g., length × width × height for a rectangular piece). Density varies by metal — aluminium is 2,700 kg/m³, copper is 8,960 kg/m³, titanium is 4,507 kg/m³.
Which metal is lighter — aluminium or steel?
Aluminium (2,700 kg/m³) is about 1/3 the density of steel (7,850 kg/m³). This is why aircraft and automotive parts use aluminium — the same volume weighs much less. However, steel is stronger per unit volume.
What is the density of copper?
Copper density = 8,960 kg/m³ (8.96 g/cm³). A 1m × 1m × 10mm copper sheet weighs 89.6 kg. Copper is heavier than steel by volume, which is why copper plumbing and wiring is more expensive by weight per metre.
What is the density of aluminium?
Aluminium density = 2,700 kg/m³ (2.7 g/cm³) — roughly 1/3 of steel and 1/3 of copper. An aluminium 1m × 1m × 10mm sheet weighs only 27 kg, compared to 78.5 kg for steel. Used extensively in aerospace, packaging, and construction.
What is brass density?
Brass (copper-zinc alloy) density ≈ 8,500 kg/m³, depending on zinc content. Common brass (C260) is 8,530 kg/m³. Brass is heavier than steel but prized for its corrosion resistance, machinability, and appearance in fittings and musical instruments.
