Precious Metal AgC10 vs B685
Precious Metal · grade comparison
Precious Metal AgC10 and B685 are both precious metal grades. B685 is the stronger of the two: yield strength 200 MPa (29 ksi) against 70 MPa (10.2 ksi) for AgC10, about 186% more; tensile strength follows at 500 MPa (72.5 ksi) vs 110 MPa (16 ksi). B685 is the more ductile: elongation 30% versus 4% for AgC10, and B685 is harder (145 HB vs 30 HB). AgC10 is lighter (7.6 g/cm³ vs 10.4 g/cm³ for B685) and B685 is stiffer (130 GPa vs 55 GPa). On the shop floor, AgC10 machines more easily (good vs poor) and B685 welds better (good vs poor).
AgC10Choose 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.
AgC10 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.

AgC10 vs B685 — frequently asked
Is B685 stronger than AgC10?
Yes. B685 has a typical yield strength of 200 MPa (29 ksi) against 70 MPa (10.2 ksi) for AgC10 — about 186% more. Tensile strength is 500 MPa (72.5 ksi) vs 110 MPa (16 ksi).
Which is cheaper, AgC10 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, AgC10 or B685?
AgC10. Its machinability rates good (55/100) against poor (30/100) for B685; for welding the order is B685 first (good, 62/100) then AgC10 (poor, 15/100).
