Precious Metal Pure Pd-H01 vs Pure Pd-O
Precious Metal · Pure Pd temper comparison
Pure Pd-H01 and Pure Pd-O are two conditions of the same precious metal grade, Pure Pd: H01 (quarter hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. Pure Pd-H01 is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 55 MPa (7.98 ksi) for Pure Pd-O, about 173% more; tensile strength follows at 235 MPa (34.1 ksi) vs 180 MPa (26.1 ksi). In exchange, Pure Pd-O is the more ductile: elongation 32% versus 15% for Pure Pd-H01, and Pure Pd-H01 is harder (62 HB vs 38 HB). Pure Pd-O runs hotter in service (500°C vs 250°C continuous).
Pure Pd-H01Choose it when strength drives the design.
Pure Pd-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Pure Pd-H01 vs Pure Pd-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.

Pure Pd-H01 vs Pure Pd-O — frequently asked
Is Pure Pd-H01 stronger than Pure Pd-O?
Yes. Pure Pd-H01 has a typical yield strength of 150 MPa (21.8 ksi) against 55 MPa (7.98 ksi) for Pure Pd-O — about 173% more. Tensile strength is 235 MPa (34.1 ksi) vs 180 MPa (26.1 ksi).
Which condition does FabDigit quote by default, H01 or O?
O is the default Pure Pd 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.
Which is easier to machine, Pure Pd-H01 or Pure Pd-O?
Pure Pd-H01, by a small margin. Both rate fair for machinability — 42/100 against 35/100 for Pure Pd-O.
