Precious Metal 92Ag-8SnO2-H04 vs 92Ag-8SnO2 PM-EXT

Precious Metal · 92Ag-8SnO2 temper comparison

92Ag-8SnO2-H04 and 92Ag-8SnO2 PM-EXT are two conditions of the same precious metal grade, 92Ag-8SnO2: H04 (full hard) versus PM-EXT (as-sintered / extruded). The chemistry is identical, so every difference below comes from the condition. 92Ag-8SnO2-H04 is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 140 MPa (20.3 ksi) for 92Ag-8SnO2 PM-EXT, about 96% more; tensile strength follows at 325 MPa (47.1 ksi) vs 245 MPa (35.5 ksi). In exchange, 92Ag-8SnO2 PM-EXT is the more ductile: elongation 15% versus 4% for 92Ag-8SnO2-H04, and 92Ag-8SnO2-H04 is harder (90 HB vs 65 HB). 92Ag-8SnO2 PM-EXT runs hotter in service (200°C vs 150°C continuous). On the shop floor, 92Ag-8SnO2-H04 machines more easily (good vs fair).

92Ag-8SnO2-H04 vs 92Ag-8SnO2 PM-EXT — frequently asked

Is 92Ag-8SnO2-H04 stronger than 92Ag-8SnO2 PM-EXT?

Yes. 92Ag-8SnO2-H04 has a typical yield strength of 275 MPa (39.9 ksi) against 140 MPa (20.3 ksi) for 92Ag-8SnO2 PM-EXT — about 96% more. Tensile strength is 325 MPa (47.1 ksi) vs 245 MPa (35.5 ksi).

Which condition does FabDigit quote by default, H04 or PM-EXT?

O is the default 92Ag-8SnO2 condition in the FabDigit quote flow (neither H04 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-H04 or 92Ag-8SnO2 PM-EXT?

92Ag-8SnO2-H04. Its machinability rates good (55/100) against fair (42/100) for 92Ag-8SnO2 PM-EXT; for welding the order is 92Ag-8SnO2-H04 first (poor, 25/100) then 92Ag-8SnO2 PM-EXT (poor, 20/100).
