Precious Metal Pd950 1/2H vs Pd950-O
Precious Metal · Pd950 temper comparison
Pd950 1/2H and Pd950-O are two conditions of the same precious metal grade, Pd950: 1/2H (half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. Pd950 1/2H is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 130 MPa (18.9 ksi) for Pd950-O, about 185% more; tensile strength follows at 450 MPa (65.3 ksi) vs 290 MPa (42.1 ksi). In exchange, Pd950-O is the more ductile: elongation 35% versus 10% for Pd950 1/2H, and Pd950 1/2H is harder (81 HB vs 45 HB). Pd950-O runs hotter in service (800°C vs 300°C continuous). On the shop floor, Pd950 1/2H machines more easily (50 vs 40 out of 100) and Pd950-O welds better (excellent vs very good).
Pd950 1/2HChoose it when strength drives the design, or when the part is machined in volume.
Pd950-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Pd950 1/2H vs Pd950-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.

Pd950 1/2H vs Pd950-O — frequently asked
Is Pd950 1/2H stronger than Pd950-O?
Yes. Pd950 1/2H has a typical yield strength of 370 MPa (53.7 ksi) against 130 MPa (18.9 ksi) for Pd950-O — about 185% more. Tensile strength is 450 MPa (65.3 ksi) vs 290 MPa (42.1 ksi).
Which condition does FabDigit quote by default, 1/2H or O?
O is the default Pd950 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, Pd950 1/2H or Pd950-O?
Pd950 1/2H, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for Pd950-O; for welding the order is Pd950-O first (excellent, 85/100) then Pd950 1/2H (very good, 75/100).
