Precious Metal 24K-F vs 24K-H01
Precious Metal · 24K temper comparison
24K-F and 24K-H01 are two conditions of the same precious metal grade, 24K: F (as fabricated) versus H01 (quarter hard). The chemistry is identical, so every difference below comes from the condition. 24K-H01 is the stronger of the two: yield strength 70 MPa (10.2 ksi) against 25 MPa (3.63 ksi) for 24K-F, about 180% more; tensile strength follows at 145 MPa (21 ksi) vs 105 MPa (15.2 ksi). 24K-H01 is harder — 34 HB against 22 HB for 24K-F — which matters for wear surfaces and threads. 24K-F runs hotter in service (600°C vs 100°C continuous).
24K-FChoose it when the part sees heat.
24K-H01Choose it when strength drives the design, or when surface hardness matters.
24K-F vs 24K-H01: 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.

24K-F vs 24K-H01 — frequently asked
Is 24K-H01 stronger than 24K-F?
Yes. 24K-H01 has a typical yield strength of 70 MPa (10.2 ksi) against 25 MPa (3.63 ksi) for 24K-F — about 180% more. Tensile strength is 145 MPa (21 ksi) vs 105 MPa (15.2 ksi).
Which condition does FabDigit quote by default, F or H01?
O is the default 24K condition in the FabDigit quote flow (neither F nor H01). 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, 24K-F or 24K-H01?
24K-H01, by a small margin. Both rate poor for machinability — 34/100 against 28/100 for 24K-F; for welding the order is 24K-H01 first (excellent, 90/100) then 24K-F (excellent, 85/100).
