Copper Alloy C73100-H01 vs C73100-H10
Copper Alloy · C73100 temper comparison
C73100-H01 and C73100-H10 are two conditions of the same copper alloy grade, C73100: H01 (quarter hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C73100-H10 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 275 MPa (39.9 ksi) for C73100-H01, about 113% more; tensile strength follows at 655 MPa (95 ksi) vs 400 MPa (58 ksi). In exchange, C73100-H01 is the more ductile: elongation 25% versus 2% for C73100-H10, and C73100-H10 is harder (210 HV vs 115 HV). C73100-H01 runs hotter in service (200°C vs 150°C continuous). On the shop floor, C73100-H01 welds better (good vs fair).
C73100-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C73100-H10Choose it when strength drives the design.
C73100-H01 vs C73100-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.

C73100-H01 vs C73100-H10 — frequently asked
Is C73100-H10 stronger than C73100-H01?
Yes. C73100-H10 has a typical yield strength of 585 MPa (84.8 ksi) against 275 MPa (39.9 ksi) for C73100-H01 — about 113% more. Tensile strength is 655 MPa (95 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, H01 or H10?
H02 is the default C73100 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, C73100-H01 or C73100-H10?
C73100-H10, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for C73100-H01; for welding the order is C73100-H01 first (good, 55/100) then C73100-H10 (fair, 40/100).
