Precious Metal 85Pt-15Ir vs AgC10
Precious Metal · grade comparison
Precious Metal 85Pt-15Ir and AgC10 are both precious metal grades. 85Pt-15Ir 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 480 MPa (69.6 ksi) vs 110 MPa (16 ksi). 85Pt-15Ir is the more ductile: elongation 27% versus 4% for AgC10. AgC10 is lighter (7.6 g/cm³ vs 21.6 g/cm³ for 85Pt-15Ir) and 85Pt-15Ir is stiffer (205 GPa vs 55 GPa). On the shop floor, AgC10 machines more easily (good vs poor) and 85Pt-15Ir welds better (very good vs poor).
85Pt-15IrChoose 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 is machined in volume.
85Pt-15Ir 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.

85Pt-15Ir vs AgC10 — frequently asked
Is 85Pt-15Ir stronger than AgC10?
Yes. 85Pt-15Ir has a typical yield strength of 200 MPa (29 ksi) against 70 MPa (10.2 ksi) for AgC10 — about 186% more. Tensile strength is 480 MPa (69.6 ksi) vs 110 MPa (16 ksi).
Which is cheaper, 85Pt-15Ir 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, 85Pt-15Ir or AgC10?
AgC10. Its machinability rates good (55/100) against poor (25/100) for 85Pt-15Ir; for welding the order is 85Pt-15Ir first (very good, 70/100) then AgC10 (poor, 15/100).
