Copper Alloy C82700-TF00 vs C82700 TF00-CAST
Copper Alloy · C82700 temper comparison
C82700-TF00 and C82700 TF00-CAST are two conditions of the same copper alloy grade, C82700: TF00 (solution heat treated and precipitation hardened) versus TF00-CAST (TF00). The chemistry is identical, so every difference below comes from the condition. C82700-TF00 is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 830 MPa (120 ksi) for C82700 TF00-CAST, about 20% more; tensile strength follows at 1,105 MPa (160 ksi) vs 930 MPa (135 ksi). In exchange, C82700 TF00-CAST is the more ductile: elongation 2% versus 1.5% for C82700-TF00, and C82700-TF00 is harder (370 HB vs 320 HB).
C82700-TF00Choose it when strength drives the design.
C82700 TF00-CASTChoose it when the part is bent, formed or impact-loaded.
C82700-TF00 vs C82700 TF00-CAST: 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.
