Use this density table to help you calculate the weight of your castings, and fabricated metal products using the formulas given throughout this site. To convert from one alloy to another divide weight by the known alloy desity and then multiply by wanted alloy density.
e.g: A ring weighing 3.0 grams in Stg wanted in 18ct Yellow. 3.0 ÷ 10.4 x 15.5 = 4.5grams | ALLOYS | DENSITY | | Wax | 0.95 | | Bronze | 9.0 | | Lead | 11.4 | | Stg Silver | 10.4 | | FINE Silver | 10.6 | | 9ct Yellow | 11.2 | | 9ct White M (medium) | 12.6 | | 9ct White S (soft) | 12.6 | | 9ct White X pal/plat | 12.9 | | 9ct Red | 11.2 | | 9ct Pink | 11.2 | | 10ct Yellow | 11.6 | | 14ct Yellow | 13.1 | | 14ct White | 12.7 | | 14ct Red | 13.1 | | 18ct Yellow | 15.5 | | 18ct Red | 15.5 | | 18ct White (soft) | 16.4 | | 18ct White (medium) | 16.4 | | 22ct Yellow | 17.7 | | 24ct Fine Gold | 19.3 | | P40 Palladium Alloy | 11.1 | | Platinum | 21.4 |
