Copper Alloy C64700-TD01 vs C64700-TF00

Copper Alloy · C64700 temper comparison

C64700-TD01 and C64700-TF00 are two conditions of the same copper alloy grade, C64700: TD01 (solution heat treated and cold worked, quarter hard) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C64700-TF00 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 310 MPa (45 ksi) for C64700-TD01, about 34% more; tensile strength follows at 550 MPa (79.8 ksi) vs 415 MPa (60.2 ksi). In exchange, C64700-TD01 is the more ductile: elongation 25% versus 18% for C64700-TF00, and C64700-TF00 is harder (165 HB vs 115 HB). C64700-TF00 runs hotter in service (200°C vs 150°C continuous) and C64700-TF00 conducts heat better (155 W/m·K vs 115 W/m·K).
