Precious Metal Pt99.95-F vs Pt99.95-H02
Precious Metal · Pt99.95 temper comparison
Pt99.95-F and Pt99.95-H02 are two conditions of the same precious metal grade, Pt99.95: F (as fabricated) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. Pt99.95-H02 is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 45 MPa (6.53 ksi) for Pt99.95-F, about 3.3 times as much; tensile strength follows at 195 MPa (28.3 ksi) vs 130 MPa (18.9 ksi). In exchange, Pt99.95-F is the more ductile: elongation 25% versus 10% for Pt99.95-H02, and Pt99.95-H02 is harder (72 HB vs 40 HB). Pt99.95-F runs hotter in service (1,500°C vs 400°C continuous).
Pt99.95-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Pt99.95-H02Choose it when strength drives the design.
Pt99.95-F vs Pt99.95-H02: 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.

Pt99.95-F vs Pt99.95-H02 — frequently asked
Is Pt99.95-H02 stronger than Pt99.95-F?
Yes. Pt99.95-H02 has a typical yield strength of 150 MPa (21.8 ksi) against 45 MPa (6.53 ksi) for Pt99.95-F — about 3.3 times as much. Tensile strength is 195 MPa (28.3 ksi) vs 130 MPa (18.9 ksi).
Which condition does FabDigit quote by default, F or H02?
Annealed is the default Pt99.95 condition in the FabDigit quote flow (neither F nor H02). 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, Pt99.95-F or Pt99.95-H02?
Pt99.95-H02, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for Pt99.95-F.
