Precious Metal PdCu Annealed vs PdCu AS-CAST
Precious Metal · PdCu temper comparison
PdCu Annealed and PdCu AS-CAST are two conditions of the same precious metal grade, PdCu: Annealed versus AS-CAST. The chemistry is identical, so every difference below comes from the condition. PdCu AS-CAST is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 240 MPa (34.8 ksi) for PdCu Annealed, about 46% more; tensile strength follows at 550 MPa (79.8 ksi) vs 500 MPa (72.5 ksi). In exchange, PdCu Annealed is the more ductile: elongation 28% versus 15% for PdCu AS-CAST, and PdCu AS-CAST is harder (165 HB vs 130 HB). PdCu Annealed conducts electricity better (5 % IACS vs 4.5 % IACS).
PdCu AnnealedChoose it when the part is bent, formed or impact-loaded.
PdCu AS-CASTChoose it when strength drives the design.
PdCu Annealed vs PdCu AS-CAST: 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 Annealed vs PdCu AS-CAST — frequently asked
Is PdCu AS-CAST stronger than PdCu Annealed?
Yes. PdCu AS-CAST has a typical yield strength of 350 MPa (50.8 ksi) against 240 MPa (34.8 ksi) for PdCu Annealed — about 46% more. Tensile strength is 550 MPa (79.8 ksi) vs 500 MPa (72.5 ksi).
Which condition does FabDigit quote by default, Annealed or AS-CAST?
Annealed is the default PdCu condition in the FabDigit quote flow. 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.
When should I choose PdCu Annealed over PdCu AS-CAST?
Pick PdCu Annealed when the part is bent, formed or impact-loaded. Pick PdCu AS-CAST when strength drives the design.
