Precious Metal Pd60Ag40 vs Pt90Ir10
Precious Metal · grade comparison
Precious Metal Pd60Ag40 and Pt90Ir10 are both precious metal grades. Pt90Ir10 is the stronger of the two: yield strength 210 MPa (30.5 ksi) against 180 MPa (26.1 ksi) for Pd60Ag40, about 17% more. In exchange, Pd60Ag40 is the more ductile: elongation 30% versus 27% for Pt90Ir10, and Pt90Ir10 is harder (105 HB vs 80 HB). Pd60Ag40 is lighter (11.35 g/cm³ vs 21.54 g/cm³ for Pt90Ir10) and Pt90Ir10 is stiffer (200 GPa vs 110 GPa). On the shop floor, Pd60Ag40 machines more easily (fair vs poor).
Pd60Ag40Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Pt90Ir10Choose it when strength drives the design, or when the part sees heat.
Pd60Ag40 vs Pt90Ir10: 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.

Pd60Ag40 vs Pt90Ir10 — frequently asked
Is Pt90Ir10 stronger than Pd60Ag40?
Yes. Pt90Ir10 has a typical yield strength of 210 MPa (30.5 ksi) against 180 MPa (26.1 ksi) for Pd60Ag40 — about 17% more. Tensile strength is 380 MPa (55.1 ksi) vs 415 MPa (60.2 ksi).
Which is cheaper, Pd60Ag40 or Pt90Ir10?
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, Pd60Ag40 or Pt90Ir10?
Pd60Ag40. Its machinability rates fair (35/100) against poor (22/100) for Pt90Ir10.
