Copper Alloy C82600-M vs C82600-TF00
Copper Alloy · C82600 temper comparison
C82600-M and C82600-TF00 are two conditions of the same copper alloy grade, C82600: M (thermomechanically controlled processed) 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 345 MPa (50 ksi) for C82600-M, about 3.0 times as much; tensile strength follows at 1,140 MPa (165 ksi) vs 550 MPa (79.8 ksi). In exchange, C82600-M is the more ductile: elongation 1.5% versus 1% for C82600-TF00, and C82600-TF00 is harder (400 HB vs 200 HB). C82600-TF00 is stiffer (131 GPa vs 124 GPa) and C82600-TF00 runs hotter in service (200°C vs 150°C continuous). On the shop floor, C82600-M machines more easily (good vs fair).
C82600-MChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
C82600-TF00Choose it when strength drives the design, or when the part sees heat.
C82600-M 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.
