Precious Metal Pt95Co5-H01 vs Pt95Co5-H02
Precious Metal · Pt95Co5 temper comparison
Pt95Co5-H01 and Pt95Co5-H02 are two conditions of the same precious metal grade, Pt95Co5: H01 (quarter hard) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. Pt95Co5-H02 is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 400 MPa (58 ksi) for Pt95Co5-H01, about 30% more; tensile strength follows at 640 MPa (92.8 ksi) vs 550 MPa (79.8 ksi). In exchange, Pt95Co5-H01 is the more ductile: elongation 15% versus 8% for Pt95Co5-H02, and Pt95Co5-H02 is harder (180 HB vs 152 HB). Pt95Co5-H01 runs hotter in service (400°C vs 350°C continuous).
Pt95Co5-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Pt95Co5-H02Choose it when strength drives the design.
Pt95Co5-H01 vs Pt95Co5-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.

Pt95Co5-H01 vs Pt95Co5-H02 — frequently asked
Is Pt95Co5-H02 stronger than Pt95Co5-H01?
Yes. Pt95Co5-H02 has a typical yield strength of 520 MPa (75.4 ksi) against 400 MPa (58 ksi) for Pt95Co5-H01 — about 30% more. Tensile strength is 640 MPa (92.8 ksi) vs 550 MPa (79.8 ksi).
Which condition does FabDigit quote by default, H01 or H02?
AC is the default Pt95Co5 condition in the FabDigit quote flow (neither H01 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, Pt95Co5-H01 or Pt95Co5-H02?
Pt95Co5-H02, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for Pt95Co5-H01; for welding the order is Pt95Co5-H01 first (very good, 80/100) then Pt95Co5-H02 (very good, 75/100).
