Precious Metal 85Pt-15Ir vs AgSnO2In2O3
Precious Metal · grade comparison
Precious Metal 85Pt-15Ir and AgSnO2In2O3 are both precious metal grades. 85Pt-15Ir is the stronger of the two: tensile strength 480 MPa (69.6 ksi) against 280 MPa (40.6 ksi) for AgSnO2In2O3, about 71% more. 85Pt-15Ir is the more ductile: elongation 27% versus 9% for AgSnO2In2O3, and 85Pt-15Ir is harder (160 HV vs 95 HV). AgSnO2In2O3 is lighter (9.95 g/cm³ vs 21.6 g/cm³ for 85Pt-15Ir) and 85Pt-15Ir is stiffer (205 GPa vs 88 GPa). On the shop floor, AgSnO2In2O3 machines more easily (fair vs poor) and 85Pt-15Ir welds better (very good vs poor).
85Pt-15IrChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
AgSnO2In2O3Choose it when weight is the constraint, or when the part is machined in volume.
85Pt-15Ir 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.

85Pt-15Ir vs AgSnO2In2O3 — frequently asked
Is 85Pt-15Ir stronger than AgSnO2In2O3?
Yes. 85Pt-15Ir has a typical tensile strength of 480 MPa (69.6 ksi) against 280 MPa (40.6 ksi) for AgSnO2In2O3 — about 71% more.
Which is cheaper, 85Pt-15Ir 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, 85Pt-15Ir or AgSnO2In2O3?
AgSnO2In2O3. Its machinability rates fair (40/100) against poor (25/100) for 85Pt-15Ir; for welding the order is 85Pt-15Ir first (very good, 70/100) then AgSnO2In2O3 (poor, 30/100).
