About these numbers. Silver alloys: compositions follow AWS A5.8/A5.8M Table 1 (ASTM B260, same UNS designations). Estimated densities are calculated from the midpoint of each alloy's composition range assuming ideal volume mixing, so those figures are estimates rather than measurements. PhosCopper alloys instead show a typical density taken from published manufacturer technical data sheets — The Harris Products Group and Lucas-Milhaupt. Where both publish a figure for the same alloy we show the higher of the two, since the difference between makers runs under 3%. BCuP-7 is the one exception: neither publishes a density for that composition, so it remains calculated. Cadmium-bearing alloys and PhosCopper alloys may differ from the figure shown by up to 15% in either direction (±15%). PhosCopper alloys in particular are prone to liquation — how a piece was cast and processed changes the result. All other alloys will differ by significantly less than that, on the order of 2% at most.
