Precious Metal 92Ag-8SnO2 vs Silver 999
Precious Metal · grade comparison
Precious Metal 92Ag-8SnO2 and Silver 999 are both precious metal grades. 92Ag-8SnO2 is the stronger of the two: yield strength 110 MPa (16 ksi) against 55 MPa (7.98 ksi) for Silver 999, about 100% more; tensile strength follows at 225 MPa (32.6 ksi) vs 140 MPa (20.3 ksi). In exchange, Silver 999 is the more ductile: elongation 48% versus 22% for 92Ag-8SnO2, and 92Ag-8SnO2 is harder (57 HB vs 25 HB). 92Ag-8SnO2 is lighter (10.1 g/cm³ vs 10.49 g/cm³ for Silver 999) and 92Ag-8SnO2 is stiffer (88 GPa vs 76 GPa). On the shop floor, Silver 999 welds better (good vs poor) and 92Ag-8SnO2 sits in a lower cost tier (high, $$$$) than Silver 999 (specialty, $$$$$).
92Ag-8SnO2Choose 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.
92Ag-8SnO2 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.
