Precious Metal Pd950 Cold Worked vs Pd950-O
Precious Metal · Pd950 temper comparison
Pd950 Cold Worked and Pd950-O are two conditions of the same precious metal grade, Pd950: Cold Worked versus O (annealed). The chemistry is identical, so every difference below comes from the condition. Pd950 Cold Worked is the stronger of the two: yield strength 510 MPa (74 ksi) against 130 MPa (18.9 ksi) for Pd950-O, about 3.9 times as much; tensile strength follows at 570 MPa (82.7 ksi) vs 290 MPa (42.1 ksi). In exchange, Pd950-O is the more ductile: elongation 35% versus 3% for Pd950 Cold Worked, and Pd950 Cold Worked is harder (110 HB vs 45 HB). Pd950-O runs hotter in service (800°C vs 300°C continuous). On the shop floor, Pd950 Cold Worked machines more easily (good vs fair) and Pd950-O welds better (excellent vs very good).
Pd950 Cold WorkedChoose 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 Cold Worked 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 Cold Worked vs Pd950-O — frequently asked
Is Pd950 Cold Worked stronger than Pd950-O?
Yes. Pd950 Cold Worked has a typical yield strength of 510 MPa (74 ksi) against 130 MPa (18.9 ksi) for Pd950-O — about 3.9 times as much. Tensile strength is 570 MPa (82.7 ksi) vs 290 MPa (42.1 ksi).
Which condition does FabDigit quote by default, Cold Worked 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 Cold Worked or Pd950-O?
Pd950 Cold Worked. Its machinability rates good (55/100) against fair (40/100) for Pd950-O; for welding the order is Pd950-O first (excellent, 85/100) then Pd950 Cold Worked (very good, 70/100).
