Precious Metal 800 Silver 1/2H vs 800 Silver Cast
Precious Metal · 800 Silver temper comparison
800 Silver 1/2H and 800 Silver Cast are two conditions of the same precious metal grade, 800 Silver: 1/2H (half hard) versus Cast (as cast). The chemistry is identical, so every difference below comes from the condition. 800 Silver 1/2H is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 115 MPa (16.7 ksi) for 800 Silver Cast, about 187% more; tensile strength follows at 400 MPa (58 ksi) vs 250 MPa (36.3 ksi). In exchange, 800 Silver Cast is the more ductile: elongation 15% versus 12% for 800 Silver 1/2H, and 800 Silver 1/2H is harder (118 HB vs 68 HB). 800 Silver Cast runs hotter in service (250°C vs 180°C continuous). On the shop floor, 800 Silver Cast welds better (very good vs good).
800 Silver 1/2HChoose it when strength drives the design.
800 Silver CastChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
800 Silver 1/2H vs 800 Silver Cast: 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 1/2H vs 800 Silver Cast — frequently asked
Is 800 Silver 1/2H stronger than 800 Silver Cast?
Yes. 800 Silver 1/2H has a typical yield strength of 330 MPa (47.9 ksi) against 115 MPa (16.7 ksi) for 800 Silver Cast — about 187% more. Tensile strength is 400 MPa (58 ksi) vs 250 MPa (36.3 ksi).
Which condition does FabDigit quote by default, 1/2H or Cast?
Annealed is the default 800 Silver condition in the FabDigit quote flow (neither 1/2H nor Cast). 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 1/2H or 800 Silver Cast?
800 Silver 1/2H. Its machinability rates good (58/100) against fair (50/100) for 800 Silver Cast; for welding the order is 800 Silver Cast first (very good, 70/100) then 800 Silver 1/2H (good, 60/100).
