Copper Alloy C72900-TF00 vs C72900-TM02

Copper Alloy · C72900 temper comparison

C72900-TF00 and C72900-TM02 are two conditions of the same copper alloy grade, C72900: TF00 (solution heat treated and precipitation hardened) versus TM02 (mill hardened, half hard). The chemistry is identical, so every difference below comes from the condition. C72900-TF00 is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 655 MPa (95 ksi) for C72900-TM02, about 53% more; tensile strength follows at 1,105 MPa (160 ksi) vs 760 MPa (110 ksi). C72900-TF00 is the more ductile: elongation 10% versus 9% for C72900-TM02, and C72900-TF00 is harder (35 HRC vs 25 HRC). C72900-TF00 runs hotter in service (250°C vs 230°C continuous). On the shop floor, C72900-TF00 machines more easily (65 vs 55 out of 100).
