Precious Metal Pt95Rh5 gauze-H04 vs Pt95Rh5 gauze-O
Precious Metal · Pt95Rh5 gauze temper comparison
Pt95Rh5 gauze-H04 and Pt95Rh5 gauze-O are two conditions of the same precious metal grade, Pt95Rh5 gauze: H04 (full hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. Pt95Rh5 gauze-H04 is the stronger of the two: yield strength 600 MPa (87 ksi) against 130 MPa (18.9 ksi) for Pt95Rh5 gauze-O, about 4.6 times as much; tensile strength follows at 690 MPa (100 ksi) vs 340 MPa (49.3 ksi). In exchange, Pt95Rh5 gauze-O is the more ductile: elongation 33% versus 2% for Pt95Rh5 gauze-H04, and Pt95Rh5 gauze-H04 is harder (143 HB vs 78 HB). Pt95Rh5 gauze-O runs hotter in service (1,200°C vs 450°C continuous). On the shop floor, Pt95Rh5 gauze-H04 machines more easily (fair vs poor) and Pt95Rh5 gauze-O welds better (excellent vs very good).

Pt95Rh5 gauze-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Pt95Rh5 gauze-H04 vs Pt95Rh5 gauze-O: 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.
