Copper Alloy C17300-TD02 vs C17300-TH01
Copper Alloy · C17300 temper comparison
C17300-TD02 and C17300-TH01 are two conditions of the same copper alloy grade, C17300: 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. C17300-TH01 is the stronger of the two: yield strength 1,105 MPa (160 ksi) against 550 MPa (79.8 ksi) for C17300-TD02, about 101% more; tensile strength follows at 1,240 MPa (180 ksi) vs 640 MPa (92.8 ksi). In exchange, C17300-TD02 is the more ductile: elongation 15% versus 4% for C17300-TH01, and C17300-TH01 is harder (375 HB vs 190 HB). C17300-TH01 runs hotter in service (200°C vs 100°C continuous) and C17300-TH01 conducts heat better (130 W/m·K vs 105 W/m·K).
C17300-TD02Choose it when the part is bent, formed or impact-loaded.
C17300-TH01Choose it when strength drives the design, or when the part sees heat.
C17300-TD02 vs C17300-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.

C17300-TD02 vs C17300-TH01 — frequently asked
Is C17300-TH01 stronger than C17300-TD02?
Yes. C17300-TH01 has a typical yield strength of 1,105 MPa (160 ksi) against 550 MPa (79.8 ksi) for C17300-TD02 — about 101% more. Tensile strength is 1,240 MPa (180 ksi) vs 640 MPa (92.8 ksi).
Which condition does FabDigit quote by default, TD02 or TH01?
A is the default C17300 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.
When should I choose C17300-TD02 over C17300-TH01?
Pick C17300-TD02 when the part is bent, formed or impact-loaded. Pick C17300-TH01 when strength drives the design, or when the part sees heat.
