Precious Metal Gold 14K Cold Worked vs Gold 14K-F
Precious Metal · Gold 14K temper comparison
Gold 14K Cold Worked and Gold 14K-F are two conditions of the same precious metal grade, Gold 14K: Cold Worked versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. Gold 14K Cold Worked is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 210 MPa (30.5 ksi) for Gold 14K-F, about 162% more; tensile strength follows at 700 MPa (102 ksi) vs 350 MPa (50.8 ksi). In exchange, Gold 14K-F is the more ductile: elongation 20% versus 4% for Gold 14K Cold Worked, and Gold 14K Cold Worked is harder (190 HB vs 133 HB). Gold 14K-F runs hotter in service (350°C vs 170°C continuous). On the shop floor, Gold 14K Cold Worked machines more easily (very good vs good).
Gold 14K Cold WorkedChoose it when strength drives the design, or when the part is machined in volume.
Gold 14K-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Gold 14K Cold Worked vs Gold 14K-F: 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.

Gold 14K Cold Worked vs Gold 14K-F — frequently asked
Is Gold 14K Cold Worked stronger than Gold 14K-F?
Yes. Gold 14K Cold Worked has a typical yield strength of 550 MPa (79.8 ksi) against 210 MPa (30.5 ksi) for Gold 14K-F — about 162% more. Tensile strength is 700 MPa (102 ksi) vs 350 MPa (50.8 ksi).
Which condition does FabDigit quote by default, Cold Worked or F?
O is the default Gold 14K condition in the FabDigit quote flow (neither Cold Worked nor F). 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, Gold 14K Cold Worked or Gold 14K-F?
Gold 14K Cold Worked. Its machinability rates very good (72/100) against good (62/100) for Gold 14K-F; for welding the order is Gold 14K-F first (very good, 72/100) then Gold 14K Cold Worked (good, 65/100).
