Copper Alloy C36700-H01 vs C36700-H02
Copper Alloy · C36700 temper comparison
C36700-H01 and C36700-H02 are two conditions of the same copper alloy grade, C36700: H01 (quarter hard) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. C36700-H02 is the stronger of the two: yield strength 345 MPa (50 ksi) against 275 MPa (39.9 ksi) for C36700-H01, about 25% more; tensile strength follows at 470 MPa (68.2 ksi) vs 425 MPa (61.6 ksi). In exchange, C36700-H01 is the more ductile: elongation 25% versus 18% for C36700-H02, and C36700-H02 is harder (145 HB vs 125 HB).
C36700-H01Choose it when the part is bent, formed or impact-loaded.
C36700-H02Choose it when strength drives the design.
C36700-H01 vs C36700-H02: 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.

C36700-H01 vs C36700-H02 — frequently asked
Is C36700-H02 stronger than C36700-H01?
Yes. C36700-H02 has a typical yield strength of 345 MPa (50 ksi) against 275 MPa (39.9 ksi) for C36700-H01 — about 25% more. Tensile strength is 470 MPa (68.2 ksi) vs 425 MPa (61.6 ksi).
Which condition does FabDigit quote by default, H01 or H02?
M20 is the default C36700 condition in the FabDigit quote flow (neither H01 nor H02). 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, C36700-H01 or C36700-H02?
C36700-H02, by a small margin. Both rate good for machinability — 65/100 against 60/100 for C36700-H01.
