Copper Alloy C82100-TB00 vs C82100-TF00
Copper Alloy · C82100 temper comparison
C82100-TB00 and C82100-TF00 are two conditions of the same copper alloy grade, C82100: TB00 (solution heat treated) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C82100-TF00 is the stronger of the two: yield strength 515 MPa (74.7 ksi) against 140 MPa (20.3 ksi) for C82100-TB00, about 3.7 times as much; tensile strength follows at 655 MPa (95 ksi) vs 310 MPa (45 ksi). In exchange, C82100-TB00 is the more ductile: elongation 25% versus 6% for C82100-TF00, and C82100-TF00 is harder (200 HB vs 80 HB). C82100-TF00 runs hotter in service (200°C vs 150°C continuous) and C82100-TF00 conducts heat better (208 W/m·K vs 90 W/m·K).
C82100-TB00Choose it when the part is bent, formed or impact-loaded.
C82100-TF00Choose it when strength drives the design, or when the part sees heat.
C82100-TB00 vs C82100-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.
