Copper Alloy C19010-H06 vs C19010-TM04
Copper Alloy · C19010 temper comparison
C19010-H06 and C19010-TM04 are two conditions of the same copper alloy grade, C19010: H06 (extra hard) versus TM04 (mill hardened, full hard). The chemistry is identical, so every difference below comes from the condition. C19010-H06 is the stronger of the two: yield strength 515 MPa (74.7 ksi) against 480 MPa (69.6 ksi) for C19010-TM04, about 7% more. In exchange, C19010-TM04 is the more ductile: elongation 8% versus 3.5% for C19010-H06, and C19010-H06 is harder (170 HV vs 155 HV). C19010-TM04 runs hotter in service (200°C vs 150°C continuous).
C19010-H06Choose it when strength drives the design.
C19010-TM04Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C19010-H06 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.

C19010-H06 vs C19010-TM04 — frequently asked
Is C19010-H06 stronger than C19010-TM04?
Yes. C19010-H06 has a typical yield strength of 515 MPa (74.7 ksi) against 480 MPa (69.6 ksi) for C19010-TM04 — about 7% more. Tensile strength is 540 MPa (78.3 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, H06 or TM04?
TM04 is the default C19010 condition in the FabDigit quote flow. 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 is easier to machine, C19010-H06 or C19010-TM04?
C19010-H06, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for C19010-TM04.
