Copper Alloy C17500-TD04 vs C17500-TF00
Copper Alloy · C17500 temper comparison
C17500-TD04 and C17500-TF00 are two conditions of the same copper alloy grade, C17500: TD04 (solution heat treated and cold worked, full hard) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C17500-TF00 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 500 MPa (72.5 ksi) for C17500-TD04, about 24% more; tensile strength follows at 760 MPa (110 ksi) vs 550 MPa (79.8 ksi). C17500-TF00 is the more ductile: elongation 15% versus 8% for C17500-TD04, and C17500-TF00 is harder (220 HB vs 160 HB). C17500-TF00 runs hotter in service (350°C vs 200°C continuous) and C17500-TF00 conducts heat better (215 W/m·K vs 110 W/m·K).
C17500-TF00Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C17500-TD04 vs C17500-TF00: 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.
