Copper Alloy C35300-H01 vs C35300-H10
Copper Alloy · C35300 temper comparison
C35300-H01 and C35300-H10 are two conditions of the same copper alloy grade, C35300: H01 (quarter hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C35300-H10 is the stronger of the two: yield strength 495 MPa (71.8 ksi) against 275 MPa (39.9 ksi) for C35300-H01, about 80% more; tensile strength follows at 570 MPa (82.7 ksi) vs 370 MPa (53.7 ksi). In exchange, C35300-H01 is the more ductile: elongation 30% versus 3% for C35300-H10, and C35300-H10 is harder (172 HB vs 95 HB).
C35300-H01Choose it when the part is bent, formed or impact-loaded.
C35300-H10Choose it when strength drives the design.
C35300-H01 vs C35300-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.

C35300-H01 vs C35300-H10 — frequently asked
Is C35300-H10 stronger than C35300-H01?
Yes. C35300-H10 has a typical yield strength of 495 MPa (71.8 ksi) against 275 MPa (39.9 ksi) for C35300-H01 — about 80% more. Tensile strength is 570 MPa (82.7 ksi) vs 370 MPa (53.7 ksi).
Which condition does FabDigit quote by default, H01 or H10?
H02 is the default C35300 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, C35300-H01 or C35300-H10?
C35300-H10. Its machinability rates very good (75/100) against good (68/100) for C35300-H01.
