Precious Metal Gold 14K vs Silver 925
Precious Metal · grade comparison
Precious Metal Gold 14K and Silver 925 are both precious metal grades, both jewelry precious metal. Gold 14K is the stronger of the two: yield strength 200 MPa (29 ksi) against 75 MPa (10.9 ksi) for Silver 925, about 167% more; tensile strength follows at 400 MPa (58 ksi) vs 280 MPa (40.6 ksi). Gold 14K is harder — 130 HB against 58 HB for Silver 925 — which matters for wear surfaces and threads. Silver 925 is lighter (10.36 g/cm³ vs 13.07 g/cm³ for Gold 14K) and Gold 14K runs hotter in service (350°C vs 200°C continuous). On the shop floor, Gold 14K welds better (very good vs good).
Gold 14KChoose it when strength drives the design, or when surface hardness matters.
Silver 925Choose it when weight is the constraint.
Gold 14K vs Silver 925: 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 vs Silver 925 — frequently asked
Is Gold 14K stronger than Silver 925?
Yes. Gold 14K has a typical yield strength of 200 MPa (29 ksi) against 75 MPa (10.9 ksi) for Silver 925 — about 167% more. Tensile strength is 400 MPa (58 ksi) vs 280 MPa (40.6 ksi).
Which is cheaper, Gold 14K or Silver 925?
Both sit in the same relative cost tier ($$$$$, specialty); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Gold 14K or Silver 925?
Gold 14K, by a small margin. Both rate good for machinability — 60/100 against 55/100 for Silver 925; for welding the order is Gold 14K first (very good, 75/100) then Silver 925 (good, 60/100).
