Precious Metal 90Ag-10Ni-H02 vs 90Ag-10Ni-O
Precious Metal · 90Ag-10Ni temper comparison
90Ag-10Ni-H02 and 90Ag-10Ni-O are two conditions of the same precious metal grade, 90Ag-10Ni: H02 (half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 90Ag-10Ni-H02 is the stronger of the two: yield strength 265 MPa (38.4 ksi) against 75 MPa (10.9 ksi) for 90Ag-10Ni-O, about 3.5 times as much; tensile strength follows at 310 MPa (45 ksi) vs 235 MPa (34.1 ksi). In exchange, 90Ag-10Ni-O is the more ductile: elongation 30% versus 6% for 90Ag-10Ni-H02, and 90Ag-10Ni-H02 is harder (85 HV vs 52 HV). On the shop floor, 90Ag-10Ni-H02 machines more easily (good vs fair).

90Ag-10Ni-H02 vs 90Ag-10Ni-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.

90Ag-10Ni-H02 vs 90Ag-10Ni-O — frequently asked
Is 90Ag-10Ni-H02 stronger than 90Ag-10Ni-O?
Yes. 90Ag-10Ni-H02 has a typical yield strength of 265 MPa (38.4 ksi) against 75 MPa (10.9 ksi) for 90Ag-10Ni-O — about 3.5 times as much. Tensile strength is 310 MPa (45 ksi) vs 235 MPa (34.1 ksi).
Which condition does FabDigit quote by default, H02 or O?
O is the default 90Ag-10Ni 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, 90Ag-10Ni-H02 or 90Ag-10Ni-O?
90Ag-10Ni-H02. Its machinability rates good (55/100) against fair (45/100) for 90Ag-10Ni-O.
