Copper Alloy C43000-H02 vs C43000-H10
Copper Alloy · C43000 temper comparison
C43000-H02 and C43000-H10 are two conditions of the same copper alloy grade, C43000: H02 (half hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C43000-H10 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 385 MPa (55.8 ksi) for C43000-H02, about 61% more; tensile strength follows at 680 MPa (98.6 ksi) vs 455 MPa (66 ksi). In exchange, C43000-H02 is the more ductile: elongation 20% versus 2% for C43000-H10, and C43000-H10 is harder (215 HV vs 140 HV). C43000-H02 runs hotter in service (150°C vs 120°C continuous).
C43000-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C43000-H10Choose it when strength drives the design.
C43000-H02 vs C43000-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.
