What is the density of aluminum?

Pure aluminum has a density of 2700 kg/m³ (2.70 g/cm³ or 0.0975 lb/in³). Common alloys vary slightly — for example, 1100 series is 2710 kg/m³, while high-strength 7075 is 2810 kg/m³ due to zinc and copper additions.

How is the aluminum sheet weight calculated?

The formula is: Weight = Length × Width × Thickness × Density. All dimensions are converted to meters first, giving a volume in m³. Multiplying by the alloy density (kg/m³) gives the weight in kilograms.

Why is aluminum so much lighter than steel?

Aluminum has a density of about 2700 kg/m³ compared to 7850 kg/m³ for carbon steel — roughly one third the weight. This makes aluminum the material of choice for weight-sensitive applications in aerospace, automotive, and marine industries.

What is the most common aluminum alloy for sheet metal?

3003 and 5052 are the most widely used sheet alloys. 3003 offers excellent formability and corrosion resistance; 5052 adds higher strength and is preferred in marine environments. 6061 is chosen when machining and structural strength are needed.

Can I calculate weight for multiple sheets at once?

Yes. Set the Quantity field to the number of sheets and the calculator multiplies the per-sheet weight by that number, displaying both total weight and individual sheet weight.

Does this calculator support imperial units?

Yes. You can enter length and width in inches or feet, and thickness in inches. The calculator converts all values to meters internally before applying the density formula.

How accurate are the results?

Results are theoretical weights based on nominal dimensions and standard alloy densities per ASTM and EN specifications. Actual weights may vary slightly due to manufacturing tolerances (typically ±3–5%).

Formula Reference

Weight (kg) = L (m) × W (m) × T (m) × ρ (kg/m³)

L = length, W = width, T = thickness, ρ = alloy density. All dimensions are converted to meters first. Aluminum density is approximately 2700 kg/m³ (2.70 g/cm³).
