Copper Alloy C82600-TB00 vs C82600-TF00
Copper Alloy · C82600 temper comparison
C82600-TB00 and C82600-TF00 are two conditions of the same copper alloy grade, C82600: TB00 (solution heat treated) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C82600-TF00 is the stronger of the two: yield strength 1,035 MPa (150 ksi) against 240 MPa (34.8 ksi) for C82600-TB00, about 4.3 times as much; tensile strength follows at 1,140 MPa (165 ksi) vs 520 MPa (75.4 ksi). In exchange, C82600-TB00 is the more ductile: elongation 20% versus 1% for C82600-TF00, and C82600-TF00 is harder (400 HB vs 120 HB). C82600-TF00 runs hotter in service (200°C vs 150°C continuous) and C82600-TF00 conducts heat better (105 W/m·K vs 80 W/m·K). On the shop floor, C82600-TB00 welds better (fair vs poor).
C82600-TB00Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C82600-TF00Choose it when strength drives the design, or when the part sees heat.
C82600-TB00 vs C82600-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.

C82600-TB00 vs C82600-TF00 — frequently asked
Is C82600-TF00 stronger than C82600-TB00?
Yes. C82600-TF00 has a typical yield strength of 1,035 MPa (150 ksi) against 240 MPa (34.8 ksi) for C82600-TB00 — about 4.3 times as much. Tensile strength is 1,140 MPa (165 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, TB00 or TF00?
TF00 is the default C82600 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, C82600-TB00 or C82600-TF00?
C82600-TB00, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for C82600-TF00; for welding the order is C82600-TB00 first (fair, 45/100) then C82600-TF00 (poor, 30/100).
