Precious Metal 835 Silver-H02 vs 835 Silver Spring
Precious Metal · 835 Silver temper comparison
835 Silver-H02 and 835 Silver Spring are two conditions of the same precious metal grade, 835 Silver: H02 (half hard) 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 375 MPa (54.4 ksi) for 835 Silver-H02, about 35% more; tensile strength follows at 560 MPa (81.2 ksi) vs 450 MPa (65.3 ksi). In exchange, 835 Silver-H02 is the more ductile: elongation 8% versus 2% for 835 Silver Spring, and 835 Silver Spring is harder (147 HB vs 110 HB). 835 Silver-H02 runs hotter in service (120°C vs 100°C continuous).
835 Silver-H02Choose 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.
835 Silver-H02 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-H02 vs 835 Silver Spring — frequently asked
Is 835 Silver Spring stronger than 835 Silver-H02?
Yes. 835 Silver Spring has a typical yield strength of 505 MPa (73.2 ksi) against 375 MPa (54.4 ksi) for 835 Silver-H02 — about 35% more. Tensile strength is 560 MPa (81.2 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, H02 or Spring?
Annealed is the default 835 Silver condition in the FabDigit quote flow (neither H02 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-H02 or 835 Silver Spring?
835 Silver Spring, by a small margin. Both rate good for machinability — 65/100 against 60/100 for 835 Silver-H02; for welding the order is 835 Silver-H02 first (good, 55/100) then 835 Silver Spring (fair, 50/100).
