Precious Metal AgC10 vs AuNi
Precious Metal · grade comparison
Precious Metal AgC10 and AuNi are both precious metal grades. AuNi is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 70 MPa (10.2 ksi) for AgC10, about 8.9 times as much; tensile strength follows at 700 MPa (102 ksi) vs 110 MPa (16 ksi). In exchange, AgC10 is the more ductile: elongation 4% versus 3% for AuNi. AgC10 is lighter (7.6 g/cm³ vs 18.3 g/cm³ for AuNi) and AuNi is stiffer (95 GPa vs 55 GPa). On the shop floor, AgC10 machines more easily (good vs fair) and AuNi welds better (very good vs poor).
AgC10Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
AuNiChoose it when strength drives the design, or when the part sees heat.
AgC10 vs AuNi: 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 AuNi — frequently asked
Is AuNi stronger than AgC10?
Yes. AuNi has a typical yield strength of 620 MPa (89.9 ksi) against 70 MPa (10.2 ksi) for AgC10 — about 8.9 times as much. Tensile strength is 700 MPa (102 ksi) vs 110 MPa (16 ksi).
Which is cheaper, AgC10 or AuNi?
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 AuNi?
AgC10. Its machinability rates good (55/100) against fair (45/100) for AuNi; for welding the order is AuNi first (very good, 75/100) then AgC10 (poor, 15/100).
