Precious Metal Argentium 935 vs IC-Ag99.99
Precious Metal · grade comparison
Precious Metal Argentium 935 and IC-Ag99.99 are both precious metal grades. Argentium 935 is the stronger of the two: yield strength 80 MPa (11.6 ksi) against 45 MPa (6.53 ksi) for IC-Ag99.99, about 78% more; tensile strength follows at 260 MPa (37.7 ksi) vs 140 MPa (20.3 ksi). Argentium 935 is harder — 48 HB against 25 HB for IC-Ag99.99 — which matters for wear surfaces and threads. IC-Ag99.99 runs hotter in service (500°C vs 200°C continuous) and IC-Ag99.99 conducts heat better (429 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 good).
Argentium 935Choose it when strength drives the design, or when surface hardness matters.
IC-Ag99.99Choose it when the part sees heat.
Argentium 935 vs IC-Ag99.99: 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.
