Precious Metal Pd950/Pd500 vs Pd99.9
Precious Metal · grade comparison
Precious Metal Pd950/Pd500 and Pd99.9 are both precious metal grades. Pd950/Pd500 is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 55 MPa (7.98 ksi) for Pd99.9, about 173% more; tensile strength follows at 320 MPa (46.4 ksi) vs 180 MPa (26.1 ksi). In exchange, Pd99.9 is the more ductile: elongation 35% versus 30% for Pd950/Pd500, and Pd950/Pd500 is harder (95 HB vs 40 HB). Pd99.9 conducts heat better (71.8 W/m·K vs 60 W/m·K). On the shop floor, Pd950/Pd500 machines more easily (fair vs poor).
Pd950/Pd500Choose it when strength drives the design, or when the part is machined in volume.
Pd99.9Choose it when the part is bent, formed or impact-loaded.
Pd950/Pd500 vs Pd99.9: 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.

Pd950/Pd500 vs Pd99.9 — frequently asked
Is Pd950/Pd500 stronger than Pd99.9?
Yes. Pd950/Pd500 has a typical yield strength of 150 MPa (21.8 ksi) against 55 MPa (7.98 ksi) for Pd99.9 — about 173% more. Tensile strength is 320 MPa (46.4 ksi) vs 180 MPa (26.1 ksi).
Which is cheaper, Pd950/Pd500 or Pd99.9?
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, Pd950/Pd500 or Pd99.9?
Pd950/Pd500. Its machinability rates fair (45/100) against poor (30/100) for Pd99.9; for welding the order is Pd99.9 first (very good, 80/100) then Pd950/Pd500 (very good, 75/100).
