Precious Metal AgC10 vs AuCo5
Precious Metal · grade comparison
Precious Metal AgC10 and AuCo5 are both precious metal grades. AuCo5 is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 70 MPa (10.2 ksi) for AgC10, about 9.3 times as much; tensile strength follows at 750 MPa (109 ksi) vs 110 MPa (16 ksi). In exchange, AgC10 is the more ductile: elongation 4% versus 3% for AuCo5. AgC10 is lighter (7.6 g/cm³ vs 18.2 g/cm³ for AuCo5) and AuCo5 is stiffer (95 GPa vs 55 GPa). On the shop floor, AgC10 machines more easily (good vs fair) and AuCo5 welds better (very good vs poor).
AgC10Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
AuCo5Choose it when strength drives the design, or when it will be welded.
AgC10 vs AuCo5: 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 AuCo5 — frequently asked
Is AuCo5 stronger than AgC10?
Yes. AuCo5 has a typical yield strength of 650 MPa (94.3 ksi) against 70 MPa (10.2 ksi) for AgC10 — about 9.3 times as much. Tensile strength is 750 MPa (109 ksi) vs 110 MPa (16 ksi).
Which is cheaper, AgC10 or AuCo5?
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 AuCo5?
AgC10. Its machinability rates good (55/100) against fair (45/100) for AuCo5; for welding the order is AuCo5 first (very good, 70/100) then AgC10 (poor, 15/100).
