Precious Metal 85Ag-15Ni-H04 vs 85Ag-15Ni-O
Precious Metal · 85Ag-15Ni temper comparison
85Ag-15Ni-H04 and 85Ag-15Ni-O are two conditions of the same precious metal grade, 85Ag-15Ni: H04 (full hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 85Ag-15Ni-H04 is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 95 MPa (13.8 ksi) for 85Ag-15Ni-O, about 3.3 times as much; tensile strength follows at 350 MPa (50.8 ksi) vs 230 MPa (33.4 ksi). In exchange, 85Ag-15Ni-O is the more ductile: elongation 25% versus 3% for 85Ag-15Ni-H04, and 85Ag-15Ni-H04 is harder (95 HB vs 57 HB). 85Ag-15Ni-O runs hotter in service (300°C vs 180°C continuous). On the shop floor, 85Ag-15Ni-H04 machines more easily (50 vs 35 out of 100).
85Ag-15Ni-H04Choose it when strength drives the design, or when the part is machined in volume.
85Ag-15Ni-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
85Ag-15Ni-H04 vs 85Ag-15Ni-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.

85Ag-15Ni-H04 vs 85Ag-15Ni-O — frequently asked
Is 85Ag-15Ni-H04 stronger than 85Ag-15Ni-O?
Yes. 85Ag-15Ni-H04 has a typical yield strength of 315 MPa (45.7 ksi) against 95 MPa (13.8 ksi) for 85Ag-15Ni-O — about 3.3 times as much. Tensile strength is 350 MPa (50.8 ksi) vs 230 MPa (33.4 ksi).
Which condition does FabDigit quote by default, H04 or O?
O is the default 85Ag-15Ni 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, 85Ag-15Ni-H04 or 85Ag-15Ni-O?
85Ag-15Ni-H04, by a small margin. Both rate fair for machinability — 50/100 against 35/100 for 85Ag-15Ni-O.
