Precious Metal 90Ag-10Ni-H01 vs 90Ag-10Ni-H08
Precious Metal · 90Ag-10Ni temper comparison
90Ag-10Ni-H01 and 90Ag-10Ni-H08 are two conditions of the same precious metal grade, 90Ag-10Ni: H01 (quarter hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. 90Ag-10Ni-H08 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 200 MPa (29 ksi) for 90Ag-10Ni-H01, about 110% more; tensile strength follows at 480 MPa (69.6 ksi) vs 275 MPa (39.9 ksi). In exchange, 90Ag-10Ni-H01 is the more ductile: elongation 12% versus 2% for 90Ag-10Ni-H08, and 90Ag-10Ni-H08 is harder (118 HB vs 67 HB). 90Ag-10Ni-H08 is stiffer (95 GPa vs 88 GPa) and 90Ag-10Ni-H01 runs hotter in service (250°C vs 150°C continuous). On the shop floor, 90Ag-10Ni-H08 welds better (good vs fair).
90Ag-10Ni-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
90Ag-10Ni-H08Choose it when strength drives the design, or when it will be welded.
90Ag-10Ni-H01 vs 90Ag-10Ni-H08: 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-H01 vs 90Ag-10Ni-H08 — frequently asked
Is 90Ag-10Ni-H08 stronger than 90Ag-10Ni-H01?
Yes. 90Ag-10Ni-H08 has a typical yield strength of 420 MPa (60.9 ksi) against 200 MPa (29 ksi) for 90Ag-10Ni-H01 — about 110% more. Tensile strength is 480 MPa (69.6 ksi) vs 275 MPa (39.9 ksi).
Which condition does FabDigit quote by default, H01 or H08?
O is the default 90Ag-10Ni condition in the FabDigit quote flow (neither H01 nor H08). 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-H01 or 90Ag-10Ni-H08?
90Ag-10Ni-H01, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 90Ag-10Ni-H08; for welding the order is 90Ag-10Ni-H08 first (good, 55/100) then 90Ag-10Ni-H01 (fair, 45/100).
