Precious Metal 90Ag-10CdO-H01 vs 90Ag-10CdO-H04
Precious Metal · 90Ag-10CdO temper comparison
90Ag-10CdO-H01 and 90Ag-10CdO-H04 are two conditions of the same precious metal grade, 90Ag-10CdO: H01 (quarter hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. 90Ag-10CdO-H04 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 180 MPa (26.1 ksi) for 90Ag-10CdO-H01, about 67% more; tensile strength follows at 340 MPa (49.3 ksi) vs 270 MPa (39.2 ksi). In exchange, 90Ag-10CdO-H01 is the more ductile: elongation 15% versus 3% for 90Ag-10CdO-H04, and 90Ag-10CdO-H04 is harder (95 HB vs 70 HB). 90Ag-10CdO-H01 runs hotter in service (220°C vs 180°C continuous).
90Ag-10CdO-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
90Ag-10CdO-H04Choose it when strength drives the design.
90Ag-10CdO-H01 vs 90Ag-10CdO-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.

90Ag-10CdO-H01 vs 90Ag-10CdO-H04 — frequently asked
Is 90Ag-10CdO-H04 stronger than 90Ag-10CdO-H01?
Yes. 90Ag-10CdO-H04 has a typical yield strength of 300 MPa (43.5 ksi) against 180 MPa (26.1 ksi) for 90Ag-10CdO-H01 — about 67% more. Tensile strength is 340 MPa (49.3 ksi) vs 270 MPa (39.2 ksi).
Which condition does FabDigit quote by default, H01 or H04?
O is the default 90Ag-10CdO condition in the FabDigit quote flow (neither H01 nor H04). 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, 90Ag-10CdO-H01 or 90Ag-10CdO-H04?
90Ag-10CdO-H04, by a small margin. Both rate good for machinability — 65/100 against 60/100 for 90Ag-10CdO-H01.
