Precious Metal Pt90Rh10 Annealed vs Pt90Rh10 ZGS-ODS
Precious Metal · Pt90Rh10 temper comparison
Pt90Rh10 Annealed and Pt90Rh10 ZGS-ODS are two conditions of the same precious metal grade, Pt90Rh10: Annealed versus ZGS-ODS (ZGS / DPH oxide-dispersion-strengthened PtRh10). The chemistry is identical, so every difference below comes from the condition. Pt90Rh10 ZGS-ODS is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 170 MPa (24.7 ksi) for Pt90Rh10 Annealed, about 29% more; tensile strength follows at 350 MPa (50.8 ksi) vs 320 MPa (46.4 ksi). In exchange, Pt90Rh10 Annealed is the more ductile: elongation 35% versus 20% for Pt90Rh10 ZGS-ODS, and Pt90Rh10 ZGS-ODS is harder (107 HB vs 88 HB). Pt90Rh10 ZGS-ODS runs hotter in service (1,600°C vs 1,450°C continuous). On the shop floor, Pt90Rh10 Annealed welds better (very good vs good).

Pt90Rh10 Annealed vs Pt90Rh10 ZGS-ODS: 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.
