What is the density of bronze?

Bronze density varies by alloy composition. Common values: commercial bronze (C220) is approximately 8,800 kg/m³, cartridge brass (C260) is 8,530 kg/m³, phosphor bronze (C510) is 8,860 kg/m³, and silicon bronze (C651) is about 8,190 kg/m³. Densities follow ASTM and CDA (Copper Development Association) standards.

How is bronze 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, which is then converted to pounds by multiplying by 2.20462.

What is the difference between bronze and brass?

Bronze is primarily a copper-tin alloy, while brass is a copper-zinc alloy. However, commercial usage sometimes blurs this — for example, C260 (cartridge brass) is primarily copper-zinc. Phosphor bronze (C510, C524) and aluminum bronze (C630, C638) are distinct families with different mechanical and corrosion properties.

Which bronze alloy is best for marine sheet applications?

Naval bronze (C464, C465) and aluminum bronze (C630) are preferred for marine applications due to excellent seawater corrosion resistance and high strength. Phosphor bronze (C510) is also widely used for marine hardware and fasteners.

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 B36 and CDA 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. Bronze densities range from approximately 7,700 kg/m³ (aluminum bronze) to 8,860 kg/m³ (phosphor bronze).
