Copper Alloy C66200-H02 vs C66200-O60
Copper Alloy · C66200 temper comparison
C66200-H02 and C66200-O60 are two conditions of the same copper alloy grade, C66200: H02 (half hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C66200-H02 is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 140 MPa (20.3 ksi) for C66200-O60, about 175% more; tensile strength follows at 485 MPa (70.3 ksi) vs 360 MPa (52.2 ksi). In exchange, C66200-O60 is the more ductile: elongation 48% versus 12% for C66200-H02, and C66200-H02 is harder (142 HB vs 85 HB).
C66200-H02Choose it when strength drives the design.
C66200-O60Choose it when the part is bent, formed or impact-loaded.
C66200-H02 vs C66200-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.

C66200-H02 vs C66200-O60 — frequently asked
Is C66200-H02 stronger than C66200-O60?
Yes. C66200-H02 has a typical yield strength of 385 MPa (55.8 ksi) against 140 MPa (20.3 ksi) for C66200-O60 — about 175% more. Tensile strength is 485 MPa (70.3 ksi) vs 360 MPa (52.2 ksi).
Which condition does FabDigit quote by default, H02 or O60?
HR02 is the default C66200 condition in the FabDigit quote flow (neither H02 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, C66200-H02 or C66200-O60?
C66200-H02, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for C66200-O60.
