Copper Alloy C22600-H01 vs C22600-H04
Copper Alloy · C22600 temper comparison
C22600-H01 and C22600-H04 are two conditions of the same copper alloy grade, C22600: H01 (quarter hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C22600-H04 is the stronger of the two: yield strength 400 MPa (58 ksi) against 276 MPa (40 ksi) for C22600-H01, about 45% more; tensile strength follows at 462 MPa (67 ksi) vs 359 MPa (52.1 ksi). In exchange, C22600-H01 is the more ductile: elongation 25% versus 5% for C22600-H04, and C22600-H04 is harder (130 HB vs 90 HB).
C22600-H01Choose it when the part is bent, formed or impact-loaded.
C22600-H04Choose it when strength drives the design.
C22600-H01 vs C22600-H04: 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.

C22600-H01 vs C22600-H04 — frequently asked
Is C22600-H04 stronger than C22600-H01?
Yes. C22600-H04 has a typical yield strength of 400 MPa (58 ksi) against 276 MPa (40 ksi) for C22600-H01 — about 45% more. Tensile strength is 462 MPa (67 ksi) vs 359 MPa (52.1 ksi).
Which condition does FabDigit quote by default, H01 or H04?
H02 is the default C22600 condition in the FabDigit quote flow (neither H01 nor H04). 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, C22600-H01 or C22600-H04?
C22600-H04. Its machinability rates fair (36/100) against poor (28/100) for C22600-H01.
