Copper Alloy C82000-M vs C82000-TF00
Copper Alloy · C82000 temper comparison
C82000-M and C82000-TF00 are two conditions of the same copper alloy grade, C82000: M (thermomechanically controlled processed) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C82000-TF00 is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 152 MPa (22 ksi) for C82000-M, about 3.3 times as much; tensile strength follows at 655 MPa (95 ksi) vs 311 MPa (45.1 ksi). In exchange, C82000-M is the more ductile: elongation 20% versus 5% for C82000-TF00, and C82000-TF00 is harder (210 HB vs 95 HB). C82000-TF00 is stiffer (138 GPa vs 124 GPa) and C82000-M runs hotter in service (250°C vs 230°C continuous). On the shop floor, C82000-M machines more easily (fair vs poor) and C82000-M welds better (good vs fair).
C82000-MChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C82000-TF00Choose it when strength drives the design.
C82000-M vs C82000-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.

C82000-M vs C82000-TF00 — frequently asked
Is C82000-TF00 stronger than C82000-M?
Yes. C82000-TF00 has a typical yield strength of 500 MPa (72.5 ksi) against 152 MPa (22 ksi) for C82000-M — about 3.3 times as much. Tensile strength is 655 MPa (95 ksi) vs 311 MPa (45.1 ksi).
Which condition does FabDigit quote by default, M or TF00?
TF00 is the default C82000 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, C82000-M or C82000-TF00?
C82000-M. Its machinability rates fair (45/100) against poor (25/100) for C82000-TF00; for welding the order is C82000-M first (good, 60/100) then C82000-TF00 (fair, 40/100).
