Precious Metal PdNi vs Pt99.95
Precious Metal · grade comparison
Precious Metal PdNi and Pt99.95 are both precious metal grades. PdNi is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 45 MPa (6.53 ksi) for Pt99.95, about 5.6 times as much; tensile strength follows at 550 MPa (79.8 ksi) vs 140 MPa (20.3 ksi). In exchange, Pt99.95 is the more ductile: elongation 40% versus 30% for PdNi, and PdNi is harder (133 HB vs 39 HB). PdNi is lighter (11.3 g/cm³ vs 21.45 g/cm³ for Pt99.95) and Pt99.95 is stiffer (168 GPa vs 140 GPa). On the shop floor, Pt99.95 welds better (excellent vs good).
PdNiChoose it when strength drives the design, or when weight is the constraint.
Pt99.95Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
PdNi vs Pt99.95: 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.

PdNi vs Pt99.95 — frequently asked
Is PdNi stronger than Pt99.95?
Yes. PdNi has a typical yield strength of 250 MPa (36.3 ksi) against 45 MPa (6.53 ksi) for Pt99.95 — about 5.6 times as much. Tensile strength is 550 MPa (79.8 ksi) vs 140 MPa (20.3 ksi).
Which is cheaper, PdNi or Pt99.95?
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, PdNi or Pt99.95?
Pt99.95. Its weldability rates excellent (90/100) against good (60/100) for PdNi.
