Copper Alloy C72500-H01 vs C72500-H14
Copper Alloy · C72500 temper comparison
C72500-H01 and C72500-H14 are two conditions of the same copper alloy grade, C72500: H01 (quarter hard) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. C72500-H14 is the stronger of the two: yield strength 725 MPa (105 ksi) against 400 MPa (58 ksi) for C72500-H01, about 81% more; tensile strength follows at 760 MPa (110 ksi) vs 470 MPa (68.2 ksi). In exchange, C72500-H01 is the more ductile: elongation 15% versus 2% for C72500-H14, and C72500-H14 is harder (235 HV vs 150 HV). C72500-H01 runs hotter in service (175°C vs 150°C continuous).
C72500-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C72500-H14Choose it when strength drives the design.
C72500-H01 vs C72500-H14: 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.

C72500-H01 vs C72500-H14 — frequently asked
Is C72500-H14 stronger than C72500-H01?
Yes. C72500-H14 has a typical yield strength of 725 MPa (105 ksi) against 400 MPa (58 ksi) for C72500-H01 — about 81% more. Tensile strength is 760 MPa (110 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, H01 or H14?
H02 is the default C72500 condition in the FabDigit quote flow (neither H01 nor H14). 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, C72500-H01 or C72500-H14?
C72500-H14. Its machinability rates fair (35/100) against poor (30/100) for C72500-H01.
