Precious Metal PdCu AS-CAST vs PdCu-H04
Precious Metal · PdCu temper comparison
PdCu AS-CAST and PdCu-H04 are two conditions of the same precious metal grade, PdCu: AS-CAST versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. PdCu-H04 is the stronger of the two: yield strength 800 MPa (116 ksi) against 350 MPa (50.8 ksi) for PdCu AS-CAST, about 129% more; tensile strength follows at 900 MPa (131 ksi) vs 550 MPa (79.8 ksi). In exchange, PdCu AS-CAST is the more ductile: elongation 15% versus 3% for PdCu-H04, and PdCu AS-CAST is harder (165 HB vs 130 HB). On the shop floor, PdCu-H04 machines more easily (fair vs poor).
PdCu AS-CASTChoose it when the part is bent, formed or impact-loaded.
PdCu-H04Choose it when strength drives the design, or when the part is machined in volume.
PdCu AS-CAST vs PdCu-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.

PdCu AS-CAST vs PdCu-H04 — frequently asked
Is PdCu-H04 stronger than PdCu AS-CAST?
Yes. PdCu-H04 has a typical yield strength of 800 MPa (116 ksi) against 350 MPa (50.8 ksi) for PdCu AS-CAST — about 129% more. Tensile strength is 900 MPa (131 ksi) vs 550 MPa (79.8 ksi).
Which condition does FabDigit quote by default, AS-CAST or H04?
Annealed is the default PdCu condition in the FabDigit quote flow (neither AS-CAST 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 is easier to machine, PdCu AS-CAST or PdCu-H04?
PdCu-H04. Its machinability rates fair (45/100) against poor (30/100) for PdCu AS-CAST.
