Copper Alloy C42600-H01 vs C42600-H10
Copper Alloy · C42600 temper comparison
C42600-H01 and C42600-H10 are two conditions of the same copper alloy grade, C42600: H01 (quarter hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C42600-H10 is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 300 MPa (43.5 ksi) for C42600-H01, about 93% more; tensile strength follows at 620 MPa (89.9 ksi) vs 400 MPa (58 ksi). In exchange, C42600-H01 is the more ductile: elongation 25% versus 2% for C42600-H10, and C42600-H10 is harder (185 HB vs 110 HB). C42600-H01 runs hotter in service (160°C vs 120°C continuous). On the shop floor, C42600-H10 machines more easily (fair vs poor).
C42600-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C42600-H10Choose it when strength drives the design, or when the part is machined in volume.
C42600-H01 vs C42600-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.

C42600-H01 vs C42600-H10 — frequently asked
Is C42600-H10 stronger than C42600-H01?
Yes. C42600-H10 has a typical yield strength of 580 MPa (84.1 ksi) against 300 MPa (43.5 ksi) for C42600-H01 — about 93% more. Tensile strength is 620 MPa (89.9 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, H01 or H10?
H02 is the default C42600 condition in the FabDigit quote flow (neither H01 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, C42600-H01 or C42600-H10?
C42600-H10. Its machinability rates fair (44/100) against poor (33/100) for C42600-H01.
