Precious Metal AgSnO2In2O3 vs B628
Precious Metal · grade comparison
Precious Metal AgSnO2In2O3 and B628 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 B628, about 58% more. In exchange, B628 is the more ductile: elongation 25% versus 9% for AgSnO2In2O3, and AgSnO2In2O3 is harder (90 HB vs 62 HB). B628 runs hotter in service (300°C vs 250°C continuous) and B628 conducts heat better (360 W/m·K vs 320 W/m·K). On the shop floor, B628 machines more easily (good vs fair) and B628 welds better (good vs poor).
AgSnO2In2O3Choose it when strength drives the design.
B628Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
AgSnO2In2O3 vs B628: 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 B628 — frequently asked
Is AgSnO2In2O3 stronger than B628?
Yes. AgSnO2In2O3 has a typical yield strength of 205 MPa (29.7 ksi) against 130 MPa (18.9 ksi) for B628 — about 58% more. Tensile strength is 280 MPa (40.6 ksi) vs 280 MPa (40.6 ksi).
Which is cheaper, AgSnO2In2O3 or B628?
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 B628?
B628. Its machinability rates good (55/100) against fair (40/100) for AgSnO2In2O3; for welding the order is B628 first (good, 55/100) then AgSnO2In2O3 (poor, 30/100).
