Precious Metal 92Ag-8SnO2-H02 vs 92Ag-8SnO2-O
Precious Metal · 92Ag-8SnO2 temper comparison
92Ag-8SnO2-H02 and 92Ag-8SnO2-O are two conditions of the same precious metal grade, 92Ag-8SnO2: H02 (half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. 92Ag-8SnO2-H02 is the stronger of the two: yield strength 200 MPa (29 ksi) against 110 MPa (16 ksi) for 92Ag-8SnO2-O, about 82% more; tensile strength follows at 275 MPa (39.9 ksi) vs 225 MPa (32.6 ksi). In exchange, 92Ag-8SnO2-O is the more ductile: elongation 22% versus 8% for 92Ag-8SnO2-H02, and 92Ag-8SnO2-H02 is harder (74 HB vs 57 HB). 92Ag-8SnO2-O runs hotter in service (250°C vs 180°C continuous).
92Ag-8SnO2-H02Choose it when strength drives the design.
92Ag-8SnO2-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
92Ag-8SnO2-H02 vs 92Ag-8SnO2-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.
