Copper Alloy C82500-TB00 vs C82500-TF00
Copper Alloy · C82500 temper comparison
C82500-TB00 and C82500-TF00 are two conditions of the same copper alloy grade, C82500: TB00 (solution heat treated) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C82500-TF00 is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 205 MPa (29.7 ksi) for C82500-TB00, about 4.9 times as much; tensile strength follows at 1,105 MPa (160 ksi) vs 480 MPa (69.6 ksi). In exchange, C82500-TB00 is the more ductile: elongation 25% versus 1% for C82500-TF00, and C82500-TF00 is harder (375 HB vs 115 HB). C82500-TF00 runs hotter in service (250°C vs 150°C continuous) and C82500-TF00 conducts heat better (105 W/m·K vs 84 W/m·K). On the shop floor, C82500-TF00 machines more easily (fair vs poor) and C82500-TB00 welds better (good vs fair).
C82500-TB00Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C82500-TF00Choose it when strength drives the design, or when the part sees heat.
C82500-TB00 vs C82500-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.

C82500-TB00 vs C82500-TF00 — frequently asked
Is C82500-TF00 stronger than C82500-TB00?
Yes. C82500-TF00 has a typical yield strength of 1,000 MPa (145 ksi) against 205 MPa (29.7 ksi) for C82500-TB00 — about 4.9 times as much. Tensile strength is 1,105 MPa (160 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, TB00 or TF00?
TF00 is the default C82500 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, C82500-TB00 or C82500-TF00?
C82500-TF00. Its machinability rates fair (35/100) against poor (25/100) for C82500-TB00; for welding the order is C82500-TB00 first (good, 55/100) then C82500-TF00 (fair, 40/100).
