Precious Metal 835 Silver-F vs 835 Silver Spring
Precious Metal · 835 Silver temper comparison
835 Silver-F and 835 Silver Spring are two conditions of the same precious metal grade, 835 Silver: F (as fabricated) versus Spring (spring hard). The chemistry is identical, so every difference below comes from the condition. 835 Silver Spring is the stronger of the two: yield strength 505 MPa (73.2 ksi) against 105 MPa (15.2 ksi) for 835 Silver-F, about 4.8 times as much; tensile strength follows at 560 MPa (81.2 ksi) vs 265 MPa (38.4 ksi). In exchange, 835 Silver-F is the more ductile: elongation 20% versus 2% for 835 Silver Spring, and 835 Silver Spring is harder (147 HB vs 62 HB). 835 Silver Spring is stiffer (82 GPa vs 76 GPa) and 835 Silver-F runs hotter in service (200°C vs 100°C continuous). On the shop floor, 835 Silver Spring machines more easily (65 vs 55 out of 100) and 835 Silver-F welds better (good vs fair).
835 Silver-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
835 Silver SpringChoose it when strength drives the design, or when the part is machined in volume.
835 Silver-F vs 835 Silver Spring: 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.

835 Silver-F vs 835 Silver Spring — frequently asked
Is 835 Silver Spring stronger than 835 Silver-F?
Yes. 835 Silver Spring has a typical yield strength of 505 MPa (73.2 ksi) against 105 MPa (15.2 ksi) for 835 Silver-F — about 4.8 times as much. Tensile strength is 560 MPa (81.2 ksi) vs 265 MPa (38.4 ksi).
Which condition does FabDigit quote by default, F or Spring?
Annealed is the default 835 Silver condition in the FabDigit quote flow (neither F nor Spring). 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, 835 Silver-F or 835 Silver Spring?
835 Silver Spring, by a small margin. Both rate good for machinability — 65/100 against 55/100 for 835 Silver-F; for welding the order is 835 Silver-F first (good, 60/100) then 835 Silver Spring (fair, 50/100).
