Precious Metal Pd99.9 AS-CAST vs Pd99.9-H02
Precious Metal · Pd99.9 temper comparison
Pd99.9 AS-CAST and Pd99.9-H02 are two conditions of the same precious metal grade, Pd99.9: AS-CAST versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. Pd99.9-H02 is the stronger of the two: yield strength 225 MPa (32.6 ksi) against 50 MPa (7.25 ksi) for Pd99.9 AS-CAST, about 4.5 times as much; tensile strength follows at 280 MPa (40.6 ksi) vs 165 MPa (23.9 ksi). In exchange, Pd99.9 AS-CAST is the more ductile: elongation 25% versus 8% for Pd99.9-H02, and Pd99.9-H02 is harder (84 HB vs 38 HB). Pd99.9 AS-CAST runs hotter in service (500°C vs 300°C continuous). On the shop floor, Pd99.9-H02 machines more easily (fair vs poor).
Pd99.9 AS-CASTChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Pd99.9-H02Choose it when strength drives the design, or when the part is machined in volume.
Pd99.9 AS-CAST vs Pd99.9-H02: 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.

Pd99.9 AS-CAST vs Pd99.9-H02 — frequently asked
Is Pd99.9-H02 stronger than Pd99.9 AS-CAST?
Yes. Pd99.9-H02 has a typical yield strength of 225 MPa (32.6 ksi) against 50 MPa (7.25 ksi) for Pd99.9 AS-CAST — about 4.5 times as much. Tensile strength is 280 MPa (40.6 ksi) vs 165 MPa (23.9 ksi).
Which condition does FabDigit quote by default, AS-CAST or H02?
Annealed is the default Pd99.9 condition in the FabDigit quote flow (neither AS-CAST nor H02). 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, Pd99.9 AS-CAST or Pd99.9-H02?
Pd99.9-H02. Its machinability rates fair (40/100) against poor (30/100) for Pd99.9 AS-CAST; for welding the order is Pd99.9 AS-CAST first (very good, 80/100) then Pd99.9-H02 (very good, 75/100).
