Copper Alloy C17200-TD04 vs C17200-TH01
Copper Alloy · C17200 temper comparison
C17200-TD04 and C17200-TH01 are two conditions of the same copper alloy grade, C17200: TD04 (solution heat treated and cold worked, full hard) versus TH01 (TD01 and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C17200-TH01 is the stronger of the two: yield strength 1,140 MPa (165 ksi) against 690 MPa (100 ksi) for C17200-TD04, about 65% more; tensile strength follows at 1,275 MPa (185 ksi) vs 760 MPa (110 ksi). In exchange, C17200-TD04 is the more ductile: elongation 5% versus 4% for C17200-TH01, and C17200-TH01 is harder (375 HB vs 225 HB). C17200-TH01 runs hotter in service (200°C vs 150°C continuous) and C17200-TH01 conducts heat better (125 W/m·K vs 105 W/m·K). On the shop floor, C17200-TD04 welds better (fair vs poor).
C17200-TD04Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C17200-TH01Choose it when strength drives the design, or when the part sees heat.
C17200-TD04 vs C17200-TH01: 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.

C17200-TD04 vs C17200-TH01 — frequently asked
Is C17200-TH01 stronger than C17200-TD04?
Yes. C17200-TH01 has a typical yield strength of 1,140 MPa (165 ksi) against 690 MPa (100 ksi) for C17200-TD04 — about 65% more. Tensile strength is 1,275 MPa (185 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, TD04 or TH01?
A is the default C17200 condition in the FabDigit quote flow (neither TD04 nor TH01). 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, C17200-TD04 or C17200-TH01?
C17200-TH01, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for C17200-TD04; for welding the order is C17200-TD04 first (fair, 45/100) then C17200-TH01 (poor, 30/100).
