Copper Alloy C67600-H06 vs C67600-O60
Copper Alloy · C67600 temper comparison
C67600-H06 and C67600-O60 are two conditions of the same copper alloy grade, C67600: H06 (extra hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C67600-H06 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 205 MPa (29.7 ksi) for C67600-O60, about 129% more; tensile strength follows at 680 MPa (98.6 ksi) vs 450 MPa (65.3 ksi). In exchange, C67600-O60 is the more ductile: elongation 33% versus 9% for C67600-H06, and C67600-H06 is harder (190 HB vs 105 HB). C67600-O60 runs hotter in service (200°C vs 150°C continuous). On the shop floor, C67600-H06 machines more easily (good vs fair).
C67600-H06Choose it when strength drives the design, or when the part is machined in volume.
C67600-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C67600-H06 vs C67600-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.

C67600-H06 vs C67600-O60 — frequently asked
Is C67600-H06 stronger than C67600-O60?
Yes. C67600-H06 has a typical yield strength of 470 MPa (68.2 ksi) against 205 MPa (29.7 ksi) for C67600-O60 — about 129% more. Tensile strength is 680 MPa (98.6 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, H06 or O60?
H02 is the default C67600 condition in the FabDigit quote flow (neither H06 nor O60). 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, C67600-H06 or C67600-O60?
C67600-H06. Its machinability rates good (62/100) against fair (52/100) for C67600-O60.
