Precious Metal 80Ag-20CdO vs AgSnO2In2O3
Precious Metal · grade comparison
Precious Metal 80Ag-20CdO and AgSnO2In2O3 are both precious metal grades. AgSnO2In2O3 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 135 MPa (19.6 ksi) for 80Ag-20CdO, about 52% more; tensile strength follows at 280 MPa (40.6 ksi) vs 265 MPa (38.4 ksi). In exchange, 80Ag-20CdO is the more ductile: elongation 15% versus 9% for AgSnO2In2O3, and AgSnO2In2O3 is harder (90 HB vs 66 HB).
80Ag-20CdOChoose it when the part is bent, formed or impact-loaded.
AgSnO2In2O3Choose it when strength drives the design.
80Ag-20CdO 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.

80Ag-20CdO vs AgSnO2In2O3 — frequently asked
Is AgSnO2In2O3 stronger than 80Ag-20CdO?
Yes. AgSnO2In2O3 has a typical yield strength of 205 MPa (29.7 ksi) against 135 MPa (19.6 ksi) for 80Ag-20CdO — about 52% more. Tensile strength is 280 MPa (40.6 ksi) vs 265 MPa (38.4 ksi).
Which is cheaper, 80Ag-20CdO 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, 80Ag-20CdO or AgSnO2In2O3?
80Ag-20CdO, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for AgSnO2In2O3; for welding the order is 80Ag-20CdO first (fair, 35/100) then AgSnO2In2O3 (poor, 30/100).
