Copper Alloy C11600-H04 vs C11600-H10
Copper Alloy · C11600 temper comparison
C11600-H04 and C11600-H10 are two conditions of the same copper alloy grade, C11600: H04 (full hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C11600-H10 is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 310 MPa (45 ksi) for C11600-H04, about 16% more; tensile strength follows at 393 MPa (57 ksi) vs 345 MPa (50 ksi). In exchange, C11600-H04 is the more ductile: elongation 6% versus 3% for C11600-H10, and C11600-H10 is harder (110 HB vs 95 HB).

C11600-H04 vs C11600-H10: 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.

C11600-H04 vs C11600-H10 — frequently asked
Is C11600-H10 stronger than C11600-H04?
Yes. C11600-H10 has a typical yield strength of 360 MPa (52.2 ksi) against 310 MPa (45 ksi) for C11600-H04 — about 16% more. Tensile strength is 393 MPa (57 ksi) vs 345 MPa (50 ksi).
Which condition does FabDigit quote by default, H04 or H10?
H02 is the default C11600 condition in the FabDigit quote flow (neither H04 nor H10). 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, C11600-H04 or C11600-H10?
C11600-H04, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for C11600-H10.
