Precious Metal 60Pd-40Ag 1/2H vs 60Pd-40Ag Spring
Precious Metal · 60Pd-40Ag temper comparison
60Pd-40Ag 1/2H and 60Pd-40Ag Spring are two conditions of the same precious metal grade, 60Pd-40Ag: 1/2H (half hard) versus Spring (spring hard). The chemistry is identical, so every difference below comes from the condition. 60Pd-40Ag Spring is the stronger of the two: yield strength 760 MPa (110 ksi) against 540 MPa (78.3 ksi) for 60Pd-40Ag 1/2H, about 41% more; tensile strength follows at 810 MPa (117 ksi) vs 620 MPa (89.9 ksi). In exchange, 60Pd-40Ag 1/2H is the more ductile: elongation 6% versus 1.5% for 60Pd-40Ag Spring, and 60Pd-40Ag Spring is harder (195 HV vs 150 HV). 60Pd-40Ag 1/2H runs hotter in service (300°C vs 250°C continuous). On the shop floor, 60Pd-40Ag 1/2H welds better (very good vs good).
60Pd-40Ag 1/2HChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

60Pd-40Ag 1/2H vs 60Pd-40Ag Spring: 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.

60Pd-40Ag 1/2H vs 60Pd-40Ag Spring — frequently asked
Is 60Pd-40Ag Spring stronger than 60Pd-40Ag 1/2H?
Yes. 60Pd-40Ag Spring has a typical yield strength of 760 MPa (110 ksi) against 540 MPa (78.3 ksi) for 60Pd-40Ag 1/2H — about 41% more. Tensile strength is 810 MPa (117 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, 1/2H or Spring?
Annealed is the default 60Pd-40Ag condition in the FabDigit quote flow (neither 1/2H nor Spring). 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, 60Pd-40Ag 1/2H or 60Pd-40Ag Spring?
60Pd-40Ag Spring, by a small margin. Both rate fair for machinability — 52/100 against 45/100 for 60Pd-40Ag 1/2H; for welding the order is 60Pd-40Ag 1/2H first (very good, 70/100) then 60Pd-40Ag Spring (good, 60/100).
