Copper Alloy C12200-H02 vs C12200-O
Copper Alloy · C12200 temper comparison
C12200-H02 and C12200-O are two conditions of the same copper alloy grade, C12200: H02 (half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. C12200-H02 is the stronger of the two: yield strength 255 MPa (37 ksi) against 76 MPa (11 ksi) for C12200-O, about 3.4 times as much; tensile strength follows at 295 MPa (42.8 ksi) vs 235 MPa (34.1 ksi). In exchange, C12200-O is the more ductile: elongation 45% versus 14% for C12200-H02, and C12200-H02 is harder (80 HB vs 45 HB).
C12200-H02Choose it when strength drives the design.
C12200-OChoose it when the part is bent, formed or impact-loaded.
C12200-H02 vs C12200-O: 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.

C12200-H02 vs C12200-O — frequently asked
Is C12200-H02 stronger than C12200-O?
Yes. C12200-H02 has a typical yield strength of 255 MPa (37 ksi) against 76 MPa (11 ksi) for C12200-O — about 3.4 times as much. Tensile strength is 295 MPa (42.8 ksi) vs 235 MPa (34.1 ksi).
Which condition does FabDigit quote by default, H02 or O?
O is the default C12200 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, C12200-H02 or C12200-O?
C12200-H02, by a small margin. Both rate poor for machinability — 28/100 against 20/100 for C12200-O.
