Copper Alloy C17000-TD02 vs C17000-TH01
Copper Alloy · C17000 temper comparison
C17000-TD02 and C17000-TH01 are two conditions of the same copper alloy grade, C17000: TD02 (solution heat treated and cold worked, half hard) versus TH01 (TD01 and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C17000-TH01 is the stronger of the two: yield strength 1,050 MPa (152 ksi) against 570 MPa (82.7 ksi) for C17000-TD02, about 84% more; tensile strength follows at 1,180 MPa (171 ksi) vs 655 MPa (95 ksi). In exchange, C17000-TD02 is the more ductile: elongation 15% versus 5% for C17000-TH01, and C17000-TH01 is harder (345 HB vs 185 HB). C17000-TH01 runs hotter in service (200°C vs 150°C continuous) and C17000-TH01 conducts heat better (107 W/m·K vs 84 W/m·K). On the shop floor, C17000-TD02 welds better (good vs fair).
C17000-TD02Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C17000-TH01Choose it when strength drives the design, or when the part sees heat.
C17000-TD02 vs C17000-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.

C17000-TD02 vs C17000-TH01 — frequently asked
Is C17000-TH01 stronger than C17000-TD02?
Yes. C17000-TH01 has a typical yield strength of 1,050 MPa (152 ksi) against 570 MPa (82.7 ksi) for C17000-TD02 — about 84% more. Tensile strength is 1,180 MPa (171 ksi) vs 655 MPa (95 ksi).
Which condition does FabDigit quote by default, TD02 or TH01?
TF00 is the default C17000 condition in the FabDigit quote flow (neither TD02 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, C17000-TD02 or C17000-TH01?
C17000-TH01. Its machinability rates fair (40/100) against poor (33/100) for C17000-TD02; for welding the order is C17000-TD02 first (good, 55/100) then C17000-TH01 (fair, 45/100).
