Precious Metal 800 Silver Cast vs 800 Silver Spring
Precious Metal · 800 Silver temper comparison
800 Silver Cast and 800 Silver Spring are two conditions of the same precious metal grade, 800 Silver: Cast (as cast) versus Spring (spring hard). The chemistry is identical, so every difference below comes from the condition. 800 Silver Spring is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 115 MPa (16.7 ksi) for 800 Silver Cast, about 4.2 times as much; tensile strength follows at 520 MPa (75.4 ksi) vs 250 MPa (36.3 ksi). In exchange, 800 Silver Cast is the more ductile: elongation 15% versus 3% for 800 Silver Spring, and 800 Silver Spring is harder (155 HB vs 68 HB). 800 Silver Cast runs hotter in service (250°C vs 150°C continuous). On the shop floor, 800 Silver Spring machines more easily (good vs fair) and 800 Silver Cast welds better (very good vs fair).
800 Silver CastChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
800 Silver SpringChoose it when strength drives the design, or when the part is machined in volume.
800 Silver Cast vs 800 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.

800 Silver Cast vs 800 Silver Spring — frequently asked
Is 800 Silver Spring stronger than 800 Silver Cast?
Yes. 800 Silver Spring has a typical yield strength of 480 MPa (69.6 ksi) against 115 MPa (16.7 ksi) for 800 Silver Cast — about 4.2 times as much. Tensile strength is 520 MPa (75.4 ksi) vs 250 MPa (36.3 ksi).
Which condition does FabDigit quote by default, Cast or Spring?
Annealed is the default 800 Silver condition in the FabDigit quote flow (neither Cast 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, 800 Silver Cast or 800 Silver Spring?
800 Silver Spring. Its machinability rates good (62/100) against fair (50/100) for 800 Silver Cast; for welding the order is 800 Silver Cast first (very good, 70/100) then 800 Silver Spring (fair, 50/100).
