Precious Metal 10K vs 14K
Precious Metal · grade comparison
Precious Metal 10K and 14K are both precious metal grades. 14K is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 190 MPa (27.6 ksi) for 10K, about 16% more. 14K is harder — 133 HB against 118 HB for 10K — which matters for wear surfaces and threads. 10K is lighter (11.55 g/cm³ vs 13.07 g/cm³ for 14K) and 10K is stiffer (96 GPa vs 80 GPa). On the shop floor, 14K forms better (95 vs 85 out of 100).
10KChoose it when weight is the constraint, or when the part sees heat.
14KChoose it when strength drives the design, or when surface hardness matters.
10K vs 14K: 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.

10K vs 14K — frequently asked
Is 14K stronger than 10K?
Yes. 14K has a typical yield strength of 220 MPa (31.9 ksi) against 190 MPa (27.6 ksi) for 10K — about 16% more. Tensile strength is 400 MPa (58 ksi) vs 420 MPa (60.9 ksi).
Which is cheaper, 10K or 14K?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 10K or 14K?
14K. Its machinability rates good (55/100) against fair (50/100) for 10K; for welding the order is 14K first (very good, 80/100) then 10K (very good, 75/100).
