Precious Metal 85Ag-15Ni-H01 vs 85Ag-15Ni-O
Precious Metal · 85Ag-15Ni temper comparison
85Ag-15Ni-H01 and 85Ag-15Ni-O are two conditions of the same precious metal grade, 85Ag-15Ni: H01 (quarter hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 85Ag-15Ni-H01 is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 95 MPa (13.8 ksi) for 85Ag-15Ni-O, about 100% more; tensile strength follows at 270 MPa (39.2 ksi) vs 230 MPa (33.4 ksi). In exchange, 85Ag-15Ni-O is the more ductile: elongation 25% versus 13% for 85Ag-15Ni-H01, and 85Ag-15Ni-H01 is harder (71 HB vs 57 HB). 85Ag-15Ni-O runs hotter in service (300°C vs 200°C continuous).

85Ag-15Ni-H01 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-H01 vs 85Ag-15Ni-O — frequently asked
Is 85Ag-15Ni-H01 stronger than 85Ag-15Ni-O?
Yes. 85Ag-15Ni-H01 has a typical yield strength of 190 MPa (27.6 ksi) against 95 MPa (13.8 ksi) for 85Ag-15Ni-O — about 100% more. Tensile strength is 270 MPa (39.2 ksi) vs 230 MPa (33.4 ksi).
Which condition does FabDigit quote by default, H01 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-H01 or 85Ag-15Ni-O?
85Ag-15Ni-H01, by a small margin. Both rate fair for machinability — 42/100 against 35/100 for 85Ag-15Ni-O.
