Precious Metal Pd99.9 vs Pt95Rh5 gauze
Precious Metal · grade comparison
Precious Metal Pd99.9 and Pt95Rh5 gauze are both precious metal grades. Pt95Rh5 gauze is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 55 MPa (7.98 ksi) for Pd99.9, about 4.0 times as much; tensile strength follows at 420 MPa (60.9 ksi) vs 180 MPa (26.1 ksi). In exchange, Pd99.9 is the more ductile: elongation 35% versus 20% for Pt95Rh5 gauze, and Pt95Rh5 gauze is harder (85 HB vs 40 HB). Pd99.9 is lighter (12.02 g/cm³ vs 20.65 g/cm³ for Pt95Rh5 gauze) and Pt95Rh5 gauze is stiffer (180 GPa vs 121 GPa).
Pd99.9Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Pt95Rh5 gauzeChoose it when strength drives the design, or when the part sees heat.
Pd99.9 vs Pt95Rh5 gauze: 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 Pt95Rh5 gauze — frequently asked
Is Pt95Rh5 gauze stronger than Pd99.9?
Yes. Pt95Rh5 gauze has a typical yield strength of 220 MPa (31.9 ksi) against 55 MPa (7.98 ksi) for Pd99.9 — about 4.0 times as much. Tensile strength is 420 MPa (60.9 ksi) vs 180 MPa (26.1 ksi).
Which is cheaper, Pd99.9 or Pt95Rh5 gauze?
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 Pt95Rh5 gauze?
Pt95Rh5 gauze. Its weldability rates excellent (85/100) against very good (80/100) for Pd99.9.
