Precious Metal 14K Cast vs 14K-H02
Precious Metal · 14K temper comparison
14K Cast and 14K-H02 are two conditions of the same precious metal grade, 14K: Cast (as cast) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. 14K-H02 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 230 MPa (33.4 ksi) for 14K Cast, about 104% more; tensile strength follows at 600 MPa (87 ksi) vs 400 MPa (58 ksi). In exchange, 14K Cast is the more ductile: elongation 18% versus 10% for 14K-H02, and 14K-H02 is harder (176 HB vs 143 HB). 14K Cast runs hotter in service (250°C vs 180°C continuous). On the shop floor, 14K-H02 machines more easily (very good vs good).
14K CastChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
14K-H02Choose it when strength drives the design, or when the part is machined in volume.
14K Cast vs 14K-H02: 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.

14K Cast vs 14K-H02 — frequently asked
Is 14K-H02 stronger than 14K Cast?
Yes. 14K-H02 has a typical yield strength of 470 MPa (68.2 ksi) against 230 MPa (33.4 ksi) for 14K Cast — about 104% more. Tensile strength is 600 MPa (87 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, Cast or H02?
ANN is the default 14K condition in the FabDigit quote flow (neither Cast nor H02). 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, 14K Cast or 14K-H02?
14K-H02. Its machinability rates very good (70/100) against good (60/100) for 14K Cast; for welding the order is 14K Cast first (very good, 78/100) then 14K-H02 (very good, 72/100).
