Copper Alloy C54400-H02 vs C54400-H10
Copper Alloy · C54400 temper comparison
C54400-H02 and C54400-H10 are two conditions of the same copper alloy grade, C54400: H02 (half hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C54400-H10 is the stronger of the two: yield strength 565 MPa (81.9 ksi) against 275 MPa (39.9 ksi) for C54400-H02, about 105% more; tensile strength follows at 605 MPa (87.7 ksi) vs 400 MPa (58 ksi). In exchange, C54400-H02 is the more ductile: elongation 28% versus 3% for C54400-H10, and C54400-H10 is harder (190 HB vs 125 HB). C54400-H10 is stiffer (110 GPa vs 103 GPa) and C54400-H02 runs hotter in service (200°C vs 150°C continuous).
C54400-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C54400-H10Choose it when strength drives the design.
C54400-H02 vs C54400-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.

C54400-H02 vs C54400-H10 — frequently asked
Is C54400-H10 stronger than C54400-H02?
Yes. C54400-H10 has a typical yield strength of 565 MPa (81.9 ksi) against 275 MPa (39.9 ksi) for C54400-H02 — about 105% more. Tensile strength is 605 MPa (87.7 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, H02 or H10?
H04 is the default C54400 condition in the FabDigit quote flow (neither H02 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.
When should I choose C54400-H02 over C54400-H10?
Pick C54400-H02 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C54400-H10 when strength drives the design.
