Precious Metal 92Ag-8SnO2-H02 vs 92Ag-8SnO2 PM-EXT
Precious Metal · 92Ag-8SnO2 temper comparison
92Ag-8SnO2-H02 and 92Ag-8SnO2 PM-EXT are two conditions of the same precious metal grade, 92Ag-8SnO2: H02 (half hard) versus PM-EXT (as-sintered / extruded). 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 140 MPa (20.3 ksi) for 92Ag-8SnO2 PM-EXT, about 43% more; tensile strength follows at 275 MPa (39.9 ksi) vs 245 MPa (35.5 ksi). In exchange, 92Ag-8SnO2 PM-EXT is the more ductile: elongation 15% versus 8% for 92Ag-8SnO2-H02, and 92Ag-8SnO2-H02 is harder (74 HB vs 65 HB). 92Ag-8SnO2 PM-EXT runs hotter in service (200°C vs 180°C continuous).
92Ag-8SnO2-H02Choose it when strength drives the design.
92Ag-8SnO2 PM-EXTChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
92Ag-8SnO2-H02 vs 92Ag-8SnO2 PM-EXT: 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.

92Ag-8SnO2-H02 vs 92Ag-8SnO2 PM-EXT — frequently asked
Is 92Ag-8SnO2-H02 stronger than 92Ag-8SnO2 PM-EXT?
Yes. 92Ag-8SnO2-H02 has a typical yield strength of 200 MPa (29 ksi) against 140 MPa (20.3 ksi) for 92Ag-8SnO2 PM-EXT — about 43% more. Tensile strength is 275 MPa (39.9 ksi) vs 245 MPa (35.5 ksi).
Which condition does FabDigit quote by default, H02 or PM-EXT?
O is the default 92Ag-8SnO2 condition in the FabDigit quote flow (neither H02 nor PM-EXT). 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, 92Ag-8SnO2-H02 or 92Ag-8SnO2 PM-EXT?
92Ag-8SnO2-H02, by a small margin. Both rate fair for machinability — 48/100 against 42/100 for 92Ag-8SnO2 PM-EXT.
