Copper Alloy C99500-M07 vs C99500-TF00
Copper Alloy · C99500 temper comparison
C99500-M07 and C99500-TF00 are two conditions of the same copper alloy grade, C99500: M07 (as continuous cast) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C99500-TF00 is the stronger of the two: yield strength 310 MPa (45 ksi) against 255 MPa (37 ksi) for C99500-M07, about 22% more; tensile strength follows at 520 MPa (75.4 ksi) vs 480 MPa (69.6 ksi). In exchange, C99500-M07 is the more ductile: elongation 11% versus 8% for C99500-TF00, and C99500-TF00 is harder (170 HB vs 145 HB). C99500-TF00 conducts electricity better (7 % IACS vs 6 % IACS).

C99500-M07 vs C99500-TF00: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

C99500-M07 vs C99500-TF00 — frequently asked
Is C99500-TF00 stronger than C99500-M07?
Yes. C99500-TF00 has a typical yield strength of 310 MPa (45 ksi) against 255 MPa (37 ksi) for C99500-M07 — about 22% more. Tensile strength is 520 MPa (75.4 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, M07 or TF00?
M01 is the default C99500 condition in the FabDigit quote flow (neither M07 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, C99500-M07 or C99500-TF00?
C99500-M07. Its machinability rates fair (35/100) against poor (30/100) for C99500-TF00; for welding the order is C99500-M07 first (fair, 35/100) then C99500-TF00 (poor, 30/100).
