Precious Metal Pd99.9 vs Pt95W5
Precious Metal · grade comparison
Precious Metal Pd99.9 and Pt95W5 are both precious metal grades. Pt95W5 is the stronger of the two: yield strength 215 MPa (31.2 ksi) against 55 MPa (7.98 ksi) for Pd99.9, about 3.9 times as much; tensile strength follows at 480 MPa (69.6 ksi) vs 180 MPa (26.1 ksi). In exchange, Pd99.9 is the more ductile: elongation 35% versus 15% for Pt95W5, and Pt95W5 is harder (128 HB vs 40 HB). Pd99.9 is lighter (12.02 g/cm³ vs 21.3 g/cm³ for Pt95W5) and Pt95W5 is stiffer (185 GPa vs 121 GPa). On the shop floor, Pd99.9 welds better (very good vs good).
Pd99.9Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Pt95W5Choose it when strength drives the design, or when the part sees heat.
Pd99.9 vs Pt95W5: 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.

Pd99.9 vs Pt95W5 — frequently asked
Is Pt95W5 stronger than Pd99.9?
Yes. Pt95W5 has a typical yield strength of 215 MPa (31.2 ksi) against 55 MPa (7.98 ksi) for Pd99.9 — about 3.9 times as much. Tensile strength is 480 MPa (69.6 ksi) vs 180 MPa (26.1 ksi).
Which is cheaper, Pd99.9 or Pt95W5?
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 welds better, Pd99.9 or Pt95W5?
Pd99.9. Its weldability rates very good (80/100) against good (65/100) for Pt95W5.
