Precious Metal 88Ag-12SnO2 1/2H vs 88Ag-12SnO2-H
Precious Metal · 88Ag-12SnO2 temper comparison
88Ag-12SnO2 1/2H and 88Ag-12SnO2-H are two conditions of the same precious metal grade, 88Ag-12SnO2: 1/2H (half hard) versus H (hardened). The chemistry is identical, so every difference below comes from the condition. 88Ag-12SnO2-H is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 200 MPa (29 ksi) for 88Ag-12SnO2 1/2H, about 25% more; tensile strength follows at 300 MPa (43.5 ksi) vs 270 MPa (39.2 ksi). In exchange, 88Ag-12SnO2 1/2H is the more ductile: elongation 13% versus 8% for 88Ag-12SnO2-H, and 88Ag-12SnO2-H is harder (95 HB vs 81 HB).
88Ag-12SnO2 1/2HChoose it when the part is bent, formed or impact-loaded.
88Ag-12SnO2-HChoose it when strength drives the design.
88Ag-12SnO2 1/2H vs 88Ag-12SnO2-H: 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.
