Precious Metal AgSnO2In2O3 vs B780
Precious Metal · grade comparison
Precious Metal AgSnO2In2O3 and B780 are both precious metal grades. AgSnO2In2O3 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 125 MPa (18.1 ksi) for B780, about 64% more. In exchange, B780 is the more ductile: elongation 30% versus 9% for AgSnO2In2O3, and AgSnO2In2O3 is harder (90 HB vs 68 HB). B780 conducts electricity better (78 % IACS vs 66 % IACS). On the shop floor, B780 machines more easily (50 vs 40 out of 100) and B780 welds better (good vs poor).
AgSnO2In2O3Choose it when strength drives the design.
B780Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
AgSnO2In2O3 vs B780: 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 B780 — frequently asked
Is AgSnO2In2O3 stronger than B780?
Yes. AgSnO2In2O3 has a typical yield strength of 205 MPa (29.7 ksi) against 125 MPa (18.1 ksi) for B780 — about 64% more. Tensile strength is 280 MPa (40.6 ksi) vs 310 MPa (45 ksi).
Which is cheaper, AgSnO2In2O3 or B780?
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 B780?
B780, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for AgSnO2In2O3; for welding the order is B780 first (good, 60/100) then AgSnO2In2O3 (poor, 30/100).
