Precious Metal 833 Silver-F vs 833 Silver-H08
Precious Metal · 833 Silver temper comparison
833 Silver-F and 833 Silver-H08 are two conditions of the same precious metal grade, 833 Silver: F (as fabricated) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. 833 Silver-H08 is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 115 MPa (16.7 ksi) for 833 Silver-F, about 4.3 times as much; tensile strength follows at 560 MPa (81.2 ksi) vs 280 MPa (40.6 ksi). In exchange, 833 Silver-F is the more ductile: elongation 15% versus 3% for 833 Silver-H08, and 833 Silver-H08 is harder (142 HB vs 64 HB). 833 Silver-H08 is stiffer (80 GPa vs 76 GPa) and 833 Silver-F runs hotter in service (200°C vs 130°C continuous). On the shop floor, 833 Silver-H08 machines more easily (68 vs 55 out of 100) and 833 Silver-F welds better (good vs fair).
833 Silver-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
833 Silver-H08Choose it when strength drives the design, or when the part is machined in volume.
833 Silver-F vs 833 Silver-H08: 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.

833 Silver-F vs 833 Silver-H08 — frequently asked
Is 833 Silver-H08 stronger than 833 Silver-F?
Yes. 833 Silver-H08 has a typical yield strength of 500 MPa (72.5 ksi) against 115 MPa (16.7 ksi) for 833 Silver-F — about 4.3 times as much. Tensile strength is 560 MPa (81.2 ksi) vs 280 MPa (40.6 ksi).
Which condition does FabDigit quote by default, F or H08?
O is the default 833 Silver condition in the FabDigit quote flow (neither F nor H08). 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, 833 Silver-F or 833 Silver-H08?
833 Silver-H08, by a small margin. Both rate good for machinability — 68/100 against 55/100 for 833 Silver-F; for welding the order is 833 Silver-F first (good, 60/100) then 833 Silver-H08 (fair, 40/100).
