Precious Metal AgCdO12 vs Silver 999
Precious Metal · grade comparison
Precious Metal AgCdO12 and Silver 999 are both precious metal grades. AgCdO12 is the stronger of the two: yield strength 200 MPa (29 ksi) against 55 MPa (7.98 ksi) for Silver 999, about 3.6 times as much; tensile strength follows at 270 MPa (39.2 ksi) vs 140 MPa (20.3 ksi). In exchange, Silver 999 is the more ductile: elongation 48% versus 12% for AgCdO12, and AgCdO12 is harder (80 HB vs 25 HB). AgCdO12 is stiffer (80 GPa vs 76 GPa) and Silver 999 conducts heat better (429 W/m·K vs 330 W/m·K). On the shop floor, AgCdO12 machines more easily (good vs fair), Silver 999 welds better (good vs poor), and AgCdO12 sits in a lower cost tier (high, $$$$) than Silver 999 (specialty, $$$$$).
AgCdO12Choose it when strength drives the design, or when the part is machined in volume.
Silver 999Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
AgCdO12 vs Silver 999: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all precious metal grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
