Densities are the values on each alloy’s datasheet (Copper Development Association and Kupferverband/DKI data sheets; a range shows the typical spread) — the EN and ASTM standards set no density value, and real bars vary a fraction of a percent with exact chemistry. Convert to imperial by ×0.03613: CW614N 8.47 g/cm³ = 0.306 lb/in³. For part or bar mass, feed these values into the brass weight calculator.
Machining brass (8.4–8.5 g/cm³) is ~8% denser than carbon steel (7.85), noticeably lighter than copper (8.91–8.94) and three times aluminium (2.70). Within brass, lead raises density (leaded grades 8.40–8.50) and silicon lowers it — lead-free CW724R sits at 8.28–8.30 g/cm³, which slightly reduces material cost per part at equal geometry.
Density drives material cost (brass is bought by weight), freight (chargeable weight of dense small parts is real weight, not volume) and duty calculations. Every alloy above links to its full datasheet with chemistry, mechanicals and standards equivalents in the materials library.
