Copper Alloy C64710-TB00 vs C64710-TF00

Copper Alloy · C64710 temper comparison

C64710-TB00 and C64710-TF00 are two conditions of the same copper alloy grade, C64710: TB00 (solution heat treated) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C64710-TF00 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 150 MPa (21.8 ksi) for C64710-TB00, about 3.2 times as much; tensile strength follows at 620 MPa (89.9 ksi) vs 350 MPa (50.8 ksi). In exchange, C64710-TB00 is the more ductile: elongation 45% versus 15% for C64710-TF00, and C64710-TF00 is harder (180 HB vs 80 HB). C64710-TF00 runs hotter in service (230°C vs 150°C continuous) and C64710-TF00 conducts heat better (50 W/m·K vs 24 W/m·K). On the shop floor, C64710-TB00 welds better (80 vs 70 out of 100).

C64710-TB00Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

C64710-TF00Choose it when strength drives the design, or when the part sees heat.

C64710-TB00 vs C64710-TF00 — frequently asked

Is C64710-TF00 stronger than C64710-TB00?

Yes. C64710-TF00 has a typical yield strength of 480 MPa (69.6 ksi) against 150 MPa (21.8 ksi) for C64710-TB00 — about 3.2 times as much. Tensile strength is 620 MPa (89.9 ksi) vs 350 MPa (50.8 ksi).

Which condition does FabDigit quote by default, TB00 or TF00?

TF00 is the default C64710 condition in the FabDigit quote flow. 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, C64710-TB00 or C64710-TF00?

C64710-TF00, by a small margin. Both rate poor for machinability — 32/100 against 26/100 for C64710-TB00; for welding the order is C64710-TB00 first (very good, 80/100) then C64710-TF00 (very good, 70/100).
