Precious Metal 86.5Ag-13.5CdO-H02 vs 86.5Ag-13.5CdO-H04
Precious Metal · 86.5Ag-13.5CdO temper comparison
86.5Ag-13.5CdO-H02 and 86.5Ag-13.5CdO-H04 are two conditions of the same precious metal grade, 86.5Ag-13.5CdO: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. 86.5Ag-13.5CdO-H04 is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 220 MPa (31.9 ksi) for 86.5Ag-13.5CdO-H02, about 27% more; tensile strength follows at 330 MPa (47.9 ksi) vs 295 MPa (42.8 ksi). In exchange, 86.5Ag-13.5CdO-H02 is the more ductile: elongation 6% versus 3% for 86.5Ag-13.5CdO-H04, and 86.5Ag-13.5CdO-H04 is harder (95 HB vs 80 HB). 86.5Ag-13.5CdO-H02 runs hotter in service (210°C vs 180°C continuous). On the shop floor, 86.5Ag-13.5CdO-H02 welds better (very good vs good).

86.5Ag-13.5CdO-H02 vs 86.5Ag-13.5CdO-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.
