Precious Metal 70Ag-30Ni vs AgC10
Precious Metal · grade comparison
Precious Metal 70Ag-30Ni and AgC10 are both precious metal grades. 70Ag-30Ni is the stronger of the two: yield strength 110 MPa (16 ksi) against 70 MPa (10.2 ksi) for AgC10, about 57% more; tensile strength follows at 260 MPa (37.7 ksi) vs 110 MPa (16 ksi). 70Ag-30Ni is the more ductile: elongation 25% versus 4% for AgC10, and 70Ag-30Ni is harder (58 HB vs 30 HB). AgC10 is lighter (7.6 g/cm³ vs 9.95 g/cm³ for 70Ag-30Ni) and 70Ag-30Ni is stiffer (110 GPa vs 55 GPa). On the shop floor, AgC10 machines more easily (good vs fair) and 70Ag-30Ni welds better (very good vs poor).
70Ag-30NiChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
AgC10Choose it when weight is the constraint, or when the part sees heat.
70Ag-30Ni vs AgC10: 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.

70Ag-30Ni vs AgC10 — frequently asked
Is 70Ag-30Ni stronger than AgC10?
Yes. 70Ag-30Ni has a typical yield strength of 110 MPa (16 ksi) against 70 MPa (10.2 ksi) for AgC10 — about 57% more. Tensile strength is 260 MPa (37.7 ksi) vs 110 MPa (16 ksi).
Which is cheaper, 70Ag-30Ni or AgC10?
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, 70Ag-30Ni or AgC10?
AgC10. Its machinability rates good (55/100) against fair (45/100) for 70Ag-30Ni; for welding the order is 70Ag-30Ni first (very good, 70/100) then AgC10 (poor, 15/100).
