Precious Metal AgC10 vs Silver 999
Precious Metal · grade comparison
Precious Metal AgC10 and Silver 999 are both precious metal grades. AgC10 is the stronger of the two: yield strength 70 MPa (10.2 ksi) against 55 MPa (7.98 ksi) for Silver 999, about 27% more. In exchange, Silver 999 is the more ductile: elongation 48% versus 4% for AgC10, and AgC10 is harder (30 HB vs 25 HB). AgC10 is lighter (7.6 g/cm³ vs 10.49 g/cm³ for Silver 999) and Silver 999 is stiffer (76 GPa vs 55 GPa). On the shop floor, AgC10 machines more easily (good vs fair), Silver 999 welds better (good vs poor), and AgC10 sits in a lower cost tier (high, $$$$) than Silver 999 (specialty, $$$$$).
AgC10Choose it when strength drives the design, or when weight is the constraint.
Silver 999Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
AgC10 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.
