Precious Metal Pd99.9 Annealed vs Pd99.9-H01
Precious Metal · Pd99.9 temper comparison
Pd99.9 Annealed and Pd99.9-H01 are two conditions of the same precious metal grade, Pd99.9: Annealed versus H01 (quarter hard). The chemistry is identical, so every difference below comes from the condition. Pd99.9-H01 is the stronger of the two: yield strength 170 MPa (24.7 ksi) against 55 MPa (7.98 ksi) for Pd99.9 Annealed, about 3.1 times as much; tensile strength follows at 230 MPa (33.4 ksi) vs 180 MPa (26.1 ksi). In exchange, Pd99.9 Annealed is the more ductile: elongation 35% versus 16% for Pd99.9-H01, and Pd99.9-H01 is harder (64 HB vs 40 HB). Pd99.9 Annealed runs hotter in service (500°C vs 300°C continuous).
Pd99.9 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Pd99.9-H01Choose it when strength drives the design.
Pd99.9 Annealed vs Pd99.9-H01: 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.
