Copper Alloy C10100-H02 vs C10100-O
Copper Alloy · C10100 temper comparison
C10100-H02 and C10100-O are two conditions of the same copper alloy grade, C10100: H02 (half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. C10100-H02 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 69 MPa (10 ksi) for C10100-O, about 3.6 times as much; tensile strength follows at 295 MPa (42.8 ksi) vs 235 MPa (34.1 ksi). In exchange, C10100-O is the more ductile: elongation 45% versus 14% for C10100-H02, and C10100-H02 is harder (80 HB vs 45 HB). C10100-O runs hotter in service (200°C vs 150°C continuous). On the shop floor, C10100-H02 machines more easily (28 vs 18 out of 100).
C10100-H02Choose it when strength drives the design, or when the part is machined in volume.
C10100-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C10100-H02 vs C10100-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.

C10100-H02 vs C10100-O — frequently asked
Is C10100-H02 stronger than C10100-O?
Yes. C10100-H02 has a typical yield strength of 250 MPa (36.3 ksi) against 69 MPa (10 ksi) for C10100-O — about 3.6 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 C10100 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, C10100-H02 or C10100-O?
C10100-H02, by a small margin. Both rate poor for machinability — 28/100 against 18/100 for C10100-O.
