Copper Alloy C67600-H02 vs C67600-O60
Copper Alloy · C67600 temper comparison
C67600-H02 and C67600-O60 are two conditions of the same copper alloy grade, C67600: H02 (half hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C67600-H02 is the stronger of the two: yield strength 310 MPa (45 ksi) against 205 MPa (29.7 ksi) for C67600-O60, about 51% more; tensile strength follows at 565 MPa (81.9 ksi) vs 450 MPa (65.3 ksi). In exchange, C67600-O60 is the more ductile: elongation 33% versus 20% for C67600-H02, and C67600-H02 is harder (150 HB vs 105 HB). C67600-O60 runs hotter in service (200°C vs 180°C continuous).
C67600-H02Choose it when strength drives the design.
C67600-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C67600-H02 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.
