Copper Alloy C82600-M vs C82600-TB00
Copper Alloy · C82600 temper comparison
C82600-M and C82600-TB00 are two conditions of the same copper alloy grade, C82600: M (thermomechanically controlled processed) versus TB00 (solution heat treated). The chemistry is identical, so every difference below comes from the condition. C82600-M is the stronger of the two: yield strength 345 MPa (50 ksi) against 240 MPa (34.8 ksi) for C82600-TB00, about 44% more; tensile strength follows at 550 MPa (79.8 ksi) vs 520 MPa (75.4 ksi). In exchange, C82600-TB00 is the more ductile: elongation 20% versus 1.5% for C82600-M, and C82600-M is harder (200 HB vs 120 HB). C82600-TB00 is stiffer (131 GPa vs 124 GPa) and C82600-TB00 conducts heat better (80 W/m·K vs 70 W/m·K). On the shop floor, C82600-TB00 welds better (fair vs poor).
C82600-MChoose it when strength drives the design.
C82600-TB00Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C82600-M vs C82600-TB00: 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-M vs C82600-TB00 — frequently asked
Is C82600-M stronger than C82600-TB00?
Yes. C82600-M has a typical yield strength of 345 MPa (50 ksi) against 240 MPa (34.8 ksi) for C82600-TB00 — about 44% more. Tensile strength is 550 MPa (79.8 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, M or TB00?
TF00 is the default C82600 condition in the FabDigit quote flow (neither M nor TB00). 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-M or C82600-TB00?
C82600-M. Its machinability rates good (55/100) against fair (50/100) for C82600-TB00; for welding the order is C82600-TB00 first (fair, 45/100) then C82600-M (poor, 30/100).
