Copper Alloy C48600-H02 vs C48600-O60
Copper Alloy · C48600 temper comparison
C48600-H02 and C48600-O60 are two conditions of the same copper alloy grade, C48600: H02 (half hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C48600-H02 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 125 MPa (18.1 ksi) for C48600-O60, about 156% more; tensile strength follows at 440 MPa (63.8 ksi) vs 340 MPa (49.3 ksi). In exchange, C48600-O60 is the more ductile: elongation 45% versus 18% for C48600-H02, and C48600-H02 is harder (125 HB vs 75 HB). On the shop floor, C48600-H02 machines more easily (80 vs 70 out of 100).
C48600-H02Choose it when strength drives the design, or when the part is machined in volume.
C48600-O60Choose it when the part is bent, formed or impact-loaded.
C48600-H02 vs C48600-O60: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper alloy 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.

C48600-H02 vs C48600-O60 — frequently asked
Is C48600-H02 stronger than C48600-O60?
Yes. C48600-H02 has a typical yield strength of 320 MPa (46.4 ksi) against 125 MPa (18.1 ksi) for C48600-O60 — about 156% more. Tensile strength is 440 MPa (63.8 ksi) vs 340 MPa (49.3 ksi).
Which condition does FabDigit quote by default, H02 or O60?
H02 is the default C48600 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, C48600-H02 or C48600-O60?
C48600-H02, by a small margin. Both rate very good for machinability — 80/100 against 70/100 for C48600-O60.
