Copper Alloy C82500 C-TF00 vs C82500-TF00
Copper Alloy · C82500 temper comparison
C82500 C-TF00 and C82500-TF00 are two conditions of the same copper alloy grade, C82500: C-TF00 (as-cast + aged) 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 690 MPa (100 ksi) for C82500 C-TF00, about 45% more; tensile strength follows at 1,105 MPa (160 ksi) vs 860 MPa (125 ksi). In exchange, C82500 C-TF00 is the more ductile: elongation 2% versus 1% for C82500-TF00, and C82500-TF00 is harder (375 HB vs 300 HB). C82500-TF00 runs hotter in service (250°C vs 230°C continuous).
C82500 C-TF00Choose it when the part is bent, formed or impact-loaded.
C82500-TF00Choose it when strength drives the design, or when the part sees heat.
C82500 C-TF00 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.
