Copper Alloy C82000-M vs C82000-TB00
Copper Alloy · C82000 temper comparison
C82000-M and C82000-TB00 are two conditions of the same copper alloy grade, C82000: M (thermomechanically controlled processed) versus TB00 (solution heat treated). The chemistry is identical, so every difference below comes from the condition. C82000-M is the stronger of the two: yield strength 152 MPa (22 ksi) against 140 MPa (20.3 ksi) for C82000-TB00, about 9% more; tensile strength follows at 311 MPa (45.1 ksi) vs 290 MPa (42.1 ksi). In exchange, C82000-TB00 is the more ductile: elongation 25% versus 20% for C82000-M, and C82000-M is harder (95 HB vs 85 HB). C82000-TB00 is stiffer (138 GPa vs 124 GPa) and C82000-M runs hotter in service (250°C vs 150°C continuous). On the shop floor, C82000-M machines more easily (45 vs 35 out of 100) and C82000-M welds better (good vs fair).
C82000-MChoose it when strength drives the design, or when the part sees heat.
C82000-TB00Choose it when the part is bent, formed or impact-loaded.
C82000-M vs C82000-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.

C82000-M vs C82000-TB00 — frequently asked
Is C82000-M stronger than C82000-TB00?
Yes. C82000-M has a typical yield strength of 152 MPa (22 ksi) against 140 MPa (20.3 ksi) for C82000-TB00 — about 9% more. Tensile strength is 311 MPa (45.1 ksi) vs 290 MPa (42.1 ksi).
Which condition does FabDigit quote by default, M or TB00?
TF00 is the default C82000 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, C82000-M or C82000-TB00?
C82000-M, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for C82000-TB00; for welding the order is C82000-M first (good, 60/100) then C82000-TB00 (fair, 40/100).
