Copper Alloy C96700-TB00 vs C96700-TF00

Copper Alloy · C96700 temper comparison

C96700-TB00 and C96700-TF00 are two conditions of the same copper alloy grade, C96700: TB00 (solution heat treated) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C96700-TF00 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 240 MPa (34.8 ksi) for C96700-TB00, about 158% more; tensile strength follows at 760 MPa (110 ksi) vs 450 MPa (65.3 ksi). In exchange, C96700-TB00 is the more ductile: elongation 20% versus 5% for C96700-TF00, and C96700-TF00 is harder (330 HB vs 120 HB). C96700-TF00 runs hotter in service (315°C vs 150°C continuous) and C96700-TF00 conducts heat better (33 W/m·K vs 26 W/m·K). On the shop floor, C96700-TB00 machines more easily (fair vs poor) and C96700-TB00 welds better (45 vs 35 out of 100).

C96700-TB00Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

C96700-TF00Choose it when strength drives the design, or when the part sees heat.
