Precious Metal PtRu10-H02 vs PtRu10-H04
Precious Metal · PtRu10 temper comparison
PtRu10-H02 and PtRu10-H04 are two conditions of the same precious metal grade, PtRu10: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. PtRu10-H04 is the stronger of the two: yield strength 820 MPa (119 ksi) against 620 MPa (89.9 ksi) for PtRu10-H02, about 32% more; tensile strength follows at 930 MPa (135 ksi) vs 780 MPa (113 ksi). In exchange, PtRu10-H02 is the more ductile: elongation 8% versus 3% for PtRu10-H04, and PtRu10-H04 is harder (245 HB vs 208 HB). PtRu10-H02 runs hotter in service (250°C vs 200°C continuous).
PtRu10-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
PtRu10-H04Choose it when strength drives the design.
PtRu10-H02 vs PtRu10-H04: 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-H04 — frequently asked
Is PtRu10-H04 stronger than PtRu10-H02?
Yes. PtRu10-H04 has a typical yield strength of 820 MPa (119 ksi) against 620 MPa (89.9 ksi) for PtRu10-H02 — about 32% more. Tensile strength is 930 MPa (135 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, H02 or H04?
Annealed is the default PtRu10 condition in the FabDigit quote flow (neither H02 nor H04). 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 welds better, PtRu10-H02 or PtRu10-H04?
PtRu10-H02. Its weldability rates good (60/100) against good (55/100) for PtRu10-H04.
