Precious Metal PtRu10-H02 vs PtRu10 Spring
Precious Metal · PtRu10 temper comparison
PtRu10-H02 and PtRu10 Spring are two conditions of the same precious metal grade, PtRu10: H02 (half hard) versus Spring (spring hard). The chemistry is identical, so every difference below comes from the condition. PtRu10 Spring is the stronger of the two: yield strength 950 MPa (138 ksi) against 620 MPa (89.9 ksi) for PtRu10-H02, about 53% more; tensile strength follows at 1,050 MPa (152 ksi) vs 780 MPa (113 ksi). In exchange, PtRu10-H02 is the more ductile: elongation 8% versus 2% for PtRu10 Spring, and PtRu10 Spring is harder (270 HB vs 208 HB). PtRu10-H02 runs hotter in service (250°C vs 200°C continuous). On the shop floor, PtRu10-H02 welds better (good vs fair).

PtRu10-H02 vs PtRu10 Spring: 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.

PtRu10-H02 vs PtRu10 Spring — frequently asked
Is PtRu10 Spring stronger than PtRu10-H02?
Yes. PtRu10 Spring has a typical yield strength of 950 MPa (138 ksi) against 620 MPa (89.9 ksi) for PtRu10-H02 — about 53% more. Tensile strength is 1,050 MPa (152 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, H02 or Spring?
Annealed is the default PtRu10 condition in the FabDigit quote flow (neither H02 nor Spring). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, PtRu10-H02 or PtRu10 Spring?
PtRu10 Spring, by a small margin. Both rate fair for machinability — 42/100 against 36/100 for PtRu10-H02; for welding the order is PtRu10-H02 first (good, 60/100) then PtRu10 Spring (fair, 50/100).
