Copper Alloy C19000-HR08 vs C19000-TF00

Copper Alloy · C19000 temper comparison

C19000-HR08 and C19000-TF00 are two conditions of the same copper alloy grade, C19000: HR08 (spring temper, cold rolled and stress relieved) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C19000-HR08 is the stronger of the two: yield strength 586 MPa (85 ksi) against 310 MPa (45 ksi) for C19000-TF00, about 89% more; tensile strength follows at 620 MPa (89.9 ksi) vs 400 MPa (58 ksi). In exchange, C19000-TF00 is the more ductile: elongation 18% versus 3% for C19000-HR08, and C19000-HR08 is harder (190 HV vs 125 HV). C19000-TF00 runs hotter in service (250°C vs 175°C continuous) and C19000-TF00 conducts heat better (195 W/m·K vs 175 W/m·K).

C19000-HR08 vs C19000-TF00 — frequently asked

Is C19000-HR08 stronger than C19000-TF00?

Yes. C19000-HR08 has a typical yield strength of 586 MPa (85 ksi) against 310 MPa (45 ksi) for C19000-TF00 — about 89% more. Tensile strength is 620 MPa (89.9 ksi) vs 400 MPa (58 ksi).

Which condition does FabDigit quote by default, HR08 or TF00?

HR02 is the default C19000 condition in the FabDigit quote flow (neither HR08 nor TF00). 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, C19000-HR08 or C19000-TF00?

C19000-HR08, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for C19000-TF00.
