Precious Metal Pt90Rh10 Annealed vs Pt90Rh10 H-1/2
Precious Metal · Pt90Rh10 temper comparison
Pt90Rh10 Annealed and Pt90Rh10 H-1/2 are two conditions of the same precious metal grade, Pt90Rh10: Annealed versus H-1/2 (half hard). The chemistry is identical, so every difference below comes from the condition. Pt90Rh10 H-1/2 is the stronger of the two: yield strength 400 MPa (58 ksi) against 170 MPa (24.7 ksi) for Pt90Rh10 Annealed, about 135% more; tensile strength follows at 500 MPa (72.5 ksi) vs 320 MPa (46.4 ksi). In exchange, Pt90Rh10 Annealed is the more ductile: elongation 35% versus 10% for Pt90Rh10 H-1/2, and Pt90Rh10 H-1/2 is harder (152 HB vs 88 HB).

Pt90Rh10 Annealed vs Pt90Rh10 H-1/2: 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.

Pt90Rh10 Annealed vs Pt90Rh10 H-1/2 — frequently asked
Is Pt90Rh10 H-1/2 stronger than Pt90Rh10 Annealed?
Yes. Pt90Rh10 H-1/2 has a typical yield strength of 400 MPa (58 ksi) against 170 MPa (24.7 ksi) for Pt90Rh10 Annealed — about 135% more. Tensile strength is 500 MPa (72.5 ksi) vs 320 MPa (46.4 ksi).
Which condition does FabDigit quote by default, Annealed or H-1/2?
Annealed is the default Pt90Rh10 condition in the FabDigit quote flow. 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, Pt90Rh10 Annealed or Pt90Rh10 H-1/2?
Pt90Rh10 H-1/2, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for Pt90Rh10 Annealed; for welding the order is Pt90Rh10 Annealed first (very good, 75/100) then Pt90Rh10 H-1/2 (very good, 70/100).
