Copper Alloy C48600-H02 vs C48600-H04
Copper Alloy · C48600 temper comparison
C48600-H02 and C48600-H04 are two conditions of the same copper alloy grade, C48600: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C48600-H04 is the stronger of the two: yield strength 410 MPa (59.5 ksi) against 320 MPa (46.4 ksi) for C48600-H02, about 28% more; tensile strength follows at 510 MPa (74 ksi) vs 440 MPa (63.8 ksi). In exchange, C48600-H02 is the more ductile: elongation 18% versus 9% for C48600-H04, and C48600-H04 is harder (150 HB vs 125 HB).
C48600-H02Choose it when the part is bent, formed or impact-loaded.
C48600-H04Choose it when strength drives the design.
C48600-H02 vs C48600-H04: 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.
