Precious Metal 85Ag-15CdO-H02 vs 85Ag-15CdO-O
Precious Metal · 85Ag-15CdO temper comparison
85Ag-15CdO-H02 and 85Ag-15CdO-O are two conditions of the same precious metal grade, 85Ag-15CdO: H02 (half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 85Ag-15CdO-H02 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 120 MPa (17.4 ksi) for 85Ag-15CdO-O, about 108% more; tensile strength follows at 315 MPa (45.7 ksi) vs 230 MPa (33.4 ksi). In exchange, 85Ag-15CdO-O is the more ductile: elongation 20% versus 6% for 85Ag-15CdO-H02, and 85Ag-15CdO-H02 is harder (84 HB vs 58 HB). 85Ag-15CdO-O runs hotter in service (250°C vs 190°C continuous). On the shop floor, 85Ag-15CdO-H02 machines more easily (50 vs 40 out of 100).
85Ag-15CdO-H02Choose it when strength drives the design, or when the part is machined in volume.
85Ag-15CdO-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
85Ag-15CdO-H02 vs 85Ag-15CdO-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.
