Precious Metal IC-Ag99.95-H02 vs IC-Ag99.95-H04
Precious Metal · IC-Ag99.95 temper comparison
IC-Ag99.95-H02 and IC-Ag99.95-H04 are two conditions of the same precious metal grade, IC-Ag99.95: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. IC-Ag99.95-H04 is the stronger of the two: yield strength 270 MPa (39.2 ksi) against 180 MPa (26.1 ksi) for IC-Ag99.95-H02, about 50% more; tensile strength follows at 310 MPa (45 ksi) vs 240 MPa (34.8 ksi). In exchange, IC-Ag99.95-H02 is the more ductile: elongation 15% versus 5% for IC-Ag99.95-H04, and IC-Ag99.95-H04 is harder (90 HB vs 58 HB). IC-Ag99.95-H02 runs hotter in service (180°C vs 150°C continuous).
IC-Ag99.95-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
IC-Ag99.95-H04Choose it when strength drives the design.
IC-Ag99.95-H02 vs IC-Ag99.95-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.

IC-Ag99.95-H02 vs IC-Ag99.95-H04 — frequently asked
Is IC-Ag99.95-H04 stronger than IC-Ag99.95-H02?
Yes. IC-Ag99.95-H04 has a typical yield strength of 270 MPa (39.2 ksi) against 180 MPa (26.1 ksi) for IC-Ag99.95-H02 — about 50% more. Tensile strength is 310 MPa (45 ksi) vs 240 MPa (34.8 ksi).
Which condition does FabDigit quote by default, H02 or H04?
Cast is the default IC-Ag99.95 condition in the FabDigit quote flow (neither H02 nor H04). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, IC-Ag99.95-H02 or IC-Ag99.95-H04?
IC-Ag99.95-H04. Its machinability rates good (55/100) against fair (50/100) for IC-Ag99.95-H02.
