Copper Alloy C60800-O60 vs C60800-O61
Copper Alloy · C60800 temper comparison
C60800-O60 and C60800-O61 are two conditions of the same copper alloy grade, C60800: O60 (soft annealed) versus O61 (annealed). The chemistry is identical, so every difference below comes from the condition. C60800-O61 is the stronger of the two: yield strength 186 MPa (27 ksi) against 165 MPa (23.9 ksi) for C60800-O60, about 13% more. C60800-O61 is harder — 100 HB against 88 HB for C60800-O60 — which matters for wear surfaces and threads.
C60800-O61Choose it when strength drives the design, or when surface hardness matters.
C60800-O60 vs C60800-O61: 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.
