Precious Metal Gold 24K-F vs Gold 24K-H02

Precious Metal · Gold 24K temper comparison

Gold 24K-F and Gold 24K-H02 are two conditions of the same precious metal grade, Gold 24K: F (as fabricated) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. Gold 24K-H02 is the stronger of the two: yield strength 130 MPa (18.9 ksi) against 28 MPa (4.06 ksi) for Gold 24K-F, about 4.6 times as much; tensile strength follows at 170 MPa (24.7 ksi) vs 105 MPa (15.2 ksi). In exchange, Gold 24K-F is the more ductile: elongation 30% versus 15% for Gold 24K-H02, and Gold 24K-H02 is harder (43 HB vs 24 HB). Gold 24K-F runs hotter in service (700°C vs 120°C continuous). On the shop floor, Gold 24K-H02 machines more easily (50 vs 40 out of 100).

Gold 24K-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Gold 24K-H02Choose it when strength drives the design, or when the part is machined in volume.

Gold 24K-F vs Gold 24K-H02 — frequently asked

Is Gold 24K-H02 stronger than Gold 24K-F?

Yes. Gold 24K-H02 has a typical yield strength of 130 MPa (18.9 ksi) against 28 MPa (4.06 ksi) for Gold 24K-F — about 4.6 times as much. Tensile strength is 170 MPa (24.7 ksi) vs 105 MPa (15.2 ksi).

Which condition does FabDigit quote by default, F or H02?

O is the default Gold 24K 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, Gold 24K-F or Gold 24K-H02?

Gold 24K-H02, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for Gold 24K-F; for welding the order is Gold 24K-F first (excellent, 85/100) then Gold 24K-H02 (very good, 80/100).
