Precious Metal 90Ag-10SnO2 vs AgSnO2In2O3
Precious Metal · grade comparison
Precious Metal 90Ag-10SnO2 and AgSnO2In2O3 are both precious metal grades. AgSnO2In2O3 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 130 MPa (18.9 ksi) for 90Ag-10SnO2, about 58% more; tensile strength follows at 280 MPa (40.6 ksi) vs 240 MPa (34.8 ksi). In exchange, 90Ag-10SnO2 is the more ductile: elongation 18% versus 9% for AgSnO2In2O3, and AgSnO2In2O3 is harder (90 HB vs 62 HB). 90Ag-10SnO2 runs hotter in service (300°C vs 250°C continuous) and 90Ag-10SnO2 conducts heat better (370 W/m·K vs 320 W/m·K).
90Ag-10SnO2Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
AgSnO2In2O3Choose it when strength drives the design.
90Ag-10SnO2 vs AgSnO2In2O3: 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.

90Ag-10SnO2 vs AgSnO2In2O3 — frequently asked
Is AgSnO2In2O3 stronger than 90Ag-10SnO2?
Yes. AgSnO2In2O3 has a typical yield strength of 205 MPa (29.7 ksi) against 130 MPa (18.9 ksi) for 90Ag-10SnO2 — about 58% more. Tensile strength is 280 MPa (40.6 ksi) vs 240 MPa (34.8 ksi).
Which is cheaper, 90Ag-10SnO2 or AgSnO2In2O3?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 90Ag-10SnO2 or AgSnO2In2O3?
90Ag-10SnO2, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for AgSnO2In2O3; for welding the order is AgSnO2In2O3 first (poor, 30/100) then 90Ag-10SnO2 (poor, 25/100).
