Copper Alloy C19010-H02 vs C19010-TM04
Copper Alloy · C19010 temper comparison
C19010-H02 and C19010-TM04 are two conditions of the same copper alloy grade, C19010: H02 (half hard) versus TM04 (mill hardened, full hard). The chemistry is identical, so every difference below comes from the condition. C19010-TM04 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 400 MPa (58 ksi) for C19010-H02, about 20% more; tensile strength follows at 520 MPa (75.4 ksi) vs 440 MPa (63.8 ksi). In exchange, C19010-H02 is the more ductile: elongation 9% versus 8% for C19010-TM04, and C19010-TM04 is harder (155 HV vs 140 HV). C19010-TM04 runs hotter in service (200°C vs 150°C continuous).
C19010-H02Choose it when the part is bent, formed or impact-loaded.
C19010-TM04Choose it when strength drives the design, or when the part sees heat.
C19010-H02 vs C19010-TM04: 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.
