Precious Metal AgSnO2In2O3 vs B685
Precious Metal · grade comparison
Precious Metal AgSnO2In2O3 and B685 are both precious metal grades. B685 is the stronger of the two: tensile strength 500 MPa (72.5 ksi) against 280 MPa (40.6 ksi) for AgSnO2In2O3, about 79% more. B685 is the more ductile: elongation 30% versus 9% for AgSnO2In2O3, and B685 is harder (145 HB vs 90 HB). AgSnO2In2O3 is lighter (9.95 g/cm³ vs 10.4 g/cm³ for B685) and B685 is stiffer (130 GPa vs 88 GPa). On the shop floor, AgSnO2In2O3 machines more easily (fair vs poor) and B685 welds better (good vs poor).
AgSnO2In2O3Choose it when weight is the constraint, or when the part is machined in volume.
B685Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
AgSnO2In2O3 vs B685: 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.

AgSnO2In2O3 vs B685 — frequently asked
Is B685 stronger than AgSnO2In2O3?
Yes. B685 has a typical tensile strength of 500 MPa (72.5 ksi) against 280 MPa (40.6 ksi) for AgSnO2In2O3 — about 79% more.
Which is cheaper, AgSnO2In2O3 or B685?
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, AgSnO2In2O3 or B685?
AgSnO2In2O3. Its machinability rates fair (40/100) against poor (30/100) for B685; for welding the order is B685 first (good, 62/100) then AgSnO2In2O3 (poor, 30/100).
