Precious Metal IC-Ag99.99-H02 vs IC-Ag99.99-H04
Precious Metal · IC-Ag99.99 temper comparison
IC-Ag99.99-H02 and IC-Ag99.99-H04 are two conditions of the same precious metal grade, IC-Ag99.99: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. IC-Ag99.99-H04 is the stronger of the two: yield strength 270 MPa (39.2 ksi) against 175 MPa (25.4 ksi) for IC-Ag99.99-H02, about 54% more; tensile strength follows at 310 MPa (45 ksi) vs 235 MPa (34.1 ksi). In exchange, IC-Ag99.99-H02 is the more ductile: elongation 12% versus 4% for IC-Ag99.99-H04, and IC-Ag99.99-H04 is harder (82 HB vs 58 HB). IC-Ag99.99-H02 runs hotter in service (180°C vs 150°C continuous).
IC-Ag99.99-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
IC-Ag99.99-H04Choose it when strength drives the design.
IC-Ag99.99-H02 vs IC-Ag99.99-H04: 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.
