Precious Metal AgSnO2In2O3 vs Silver 999
Precious Metal · grade comparison
Precious Metal AgSnO2In2O3 and Silver 999 are both precious metal grades. AgSnO2In2O3 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 55 MPa (7.98 ksi) for Silver 999, about 3.7 times as much; tensile strength follows at 280 MPa (40.6 ksi) vs 140 MPa (20.3 ksi). In exchange, Silver 999 is the more ductile: elongation 48% versus 9% for AgSnO2In2O3, and AgSnO2In2O3 is harder (90 HB vs 25 HB). AgSnO2In2O3 is lighter (9.95 g/cm³ vs 10.49 g/cm³ for Silver 999) and AgSnO2In2O3 is stiffer (88 GPa vs 76 GPa). On the shop floor, Silver 999 welds better (good vs poor) and AgSnO2In2O3 sits in a lower cost tier (high, $$$$) than Silver 999 (specialty, $$$$$).
AgSnO2In2O3Choose 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.
AgSnO2In2O3 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.
