Precious Metal Argentium 935 vs Britannia Silver (958)
Precious Metal · grade comparison
Precious Metal Argentium 935 and Britannia Silver (958) are both precious metal grades. Argentium 935 is the stronger of the two: yield strength 80 MPa (11.6 ksi) against 60 MPa (8.7 ksi) for Britannia Silver (958), about 33% more; tensile strength follows at 260 MPa (37.7 ksi) vs 240 MPa (34.8 ksi). Britannia Silver (958) conducts heat better (385 W/m·K vs 330 W/m·K). On the shop floor, Argentium 935 machines more easily (good vs fair) and Argentium 935 welds better (excellent vs very good).
Argentium 935Choose it when strength drives the design, or when the part is machined in volume.
Argentium 935 vs Britannia Silver (958): 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.
