Precious Metal PdNi-H02 vs PdNi-H04
Precious Metal · PdNi temper comparison
PdNi-H02 and PdNi-H04 are two conditions of the same precious metal grade, PdNi: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. PdNi-H04 is the stronger of the two: yield strength 850 MPa (123 ksi) against 600 MPa (87 ksi) for PdNi-H02, about 42% more; tensile strength follows at 950 MPa (138 ksi) vs 750 MPa (109 ksi). In exchange, PdNi-H02 is the more ductile: elongation 8% versus 2% for PdNi-H04, and PdNi-H04 is harder (270 HB vs 200 HB). PdNi-H02 runs hotter in service (400°C vs 300°C continuous). On the shop floor, PdNi-H02 welds better (good vs fair).
PdNi-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
PdNi-H04Choose it when strength drives the design.
PdNi-H02 vs PdNi-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.

PdNi-H02 vs PdNi-H04 — frequently asked
Is PdNi-H04 stronger than PdNi-H02?
Yes. PdNi-H04 has a typical yield strength of 850 MPa (123 ksi) against 600 MPa (87 ksi) for PdNi-H02 — about 42% more. Tensile strength is 950 MPa (138 ksi) vs 750 MPa (109 ksi).
Which condition does FabDigit quote by default, H02 or H04?
M is the default PdNi condition in the FabDigit quote flow (neither H02 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, PdNi-H02 or PdNi-H04?
PdNi-H04, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for PdNi-H02; for welding the order is PdNi-H02 first (good, 55/100) then PdNi-H04 (fair, 45/100).
