Copper Alloy C17465-TD04 vs C17465-TH04
Copper Alloy · C17465 temper comparison
C17465-TD04 and C17465-TH04 are two conditions of the same copper alloy grade, C17465: TD04 (solution heat treated and cold worked, full hard) versus TH04 (TD04 and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C17465-TH04 is the stronger of the two: yield strength 690 MPa (100 ksi) against 480 MPa (69.6 ksi) for C17465-TD04, about 44% more; tensile strength follows at 760 MPa (110 ksi) vs 540 MPa (78.3 ksi). C17465-TH04 is the more ductile: elongation 9% versus 8% for C17465-TD04, and C17465-TH04 is harder (225 HB vs 160 HB). C17465-TH04 runs hotter in service (300°C vs 200°C continuous) and C17465-TH04 conducts heat better (220 W/m·K vs 145 W/m·K).
C17465-TH04Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C17465-TD04 vs C17465-TH04: 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.

C17465-TD04 vs C17465-TH04 — frequently asked
Is C17465-TH04 stronger than C17465-TD04?
Yes. C17465-TH04 has a typical yield strength of 690 MPa (100 ksi) against 480 MPa (69.6 ksi) for C17465-TD04 — about 44% more. Tensile strength is 760 MPa (110 ksi) vs 540 MPa (78.3 ksi).
Which condition does FabDigit quote by default, TD04 or TH04?
TF00 is the default C17465 condition in the FabDigit quote flow (neither TD04 nor TH04). 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, C17465-TD04 or C17465-TH04?
C17465-TD04, by a small margin. Both rate good for machinability — 68/100 against 62/100 for C17465-TH04; for welding the order is C17465-TD04 first (poor, 25/100) then C17465-TH04 (poor, 20/100).
