Copper Alloy C77400-H06 vs C77400-H10
Copper Alloy · C77400 temper comparison
C77400-H06 and C77400-H10 are two conditions of the same copper alloy grade, C77400: H06 (extra hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C77400-H10 is the stronger of the two: yield strength 700 MPa (102 ksi) against 620 MPa (89.9 ksi) for C77400-H06, about 13% more; tensile strength follows at 760 MPa (110 ksi) vs 690 MPa (100 ksi). In exchange, C77400-H06 is the more ductile: elongation 2% versus 1.5% for C77400-H10, and C77400-H10 is harder (223 HB vs 195 HB). C77400-H06 runs hotter in service (175°C vs 150°C continuous).
C77400-H06Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C77400-H10Choose it when strength drives the design.
C77400-H06 vs C77400-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.

C77400-H06 vs C77400-H10 — frequently asked
Is C77400-H10 stronger than C77400-H06?
Yes. C77400-H10 has a typical yield strength of 700 MPa (102 ksi) against 620 MPa (89.9 ksi) for C77400-H06 — about 13% more. Tensile strength is 760 MPa (110 ksi) vs 690 MPa (100 ksi).
Which condition does FabDigit quote by default, H06 or H10?
H02 is the default C77400 condition in the FabDigit quote flow (neither H06 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 welds better, C77400-H06 or C77400-H10?
C77400-H06. Its weldability rates fair (45/100) against fair (40/100) for C77400-H10.
