Precious Metal 90Ag-10SnO2-H2 vs 90Ag-10SnO2-O
Precious Metal · 90Ag-10SnO2 temper comparison
90Ag-10SnO2-H2 and 90Ag-10SnO2-O are two conditions of the same precious metal grade, 90Ag-10SnO2: H2 (1/2H) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 90Ag-10SnO2-H2 is the stronger of the two: yield strength 210 MPa (30.5 ksi) against 130 MPa (18.9 ksi) for 90Ag-10SnO2-O, about 62% more; tensile strength follows at 280 MPa (40.6 ksi) vs 240 MPa (34.8 ksi). In exchange, 90Ag-10SnO2-O is the more ductile: elongation 18% versus 8% for 90Ag-10SnO2-H2, and 90Ag-10SnO2-H2 is harder (76 HB vs 62 HB). 90Ag-10SnO2-O runs hotter in service (300°C vs 250°C continuous).

90Ag-10SnO2-H2 vs 90Ag-10SnO2-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-10SnO2-H2 vs 90Ag-10SnO2-O — frequently asked
Is 90Ag-10SnO2-H2 stronger than 90Ag-10SnO2-O?
Yes. 90Ag-10SnO2-H2 has a typical yield strength of 210 MPa (30.5 ksi) against 130 MPa (18.9 ksi) for 90Ag-10SnO2-O — about 62% more. Tensile strength is 280 MPa (40.6 ksi) vs 240 MPa (34.8 ksi).
Which condition does FabDigit quote by default, H2 or O?
O is the default 90Ag-10SnO2 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-10SnO2-H2 or 90Ag-10SnO2-O?
90Ag-10SnO2-O, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 90Ag-10SnO2-H2.
