Copper Alloy C82100-TF00 vs C82100 TF00-AC
Copper Alloy · C82100 temper comparison
C82100-TF00 and C82100 TF00-AC are two conditions of the same copper alloy grade, C82100: TF00 (solution heat treated and precipitation hardened) versus TF00-AC (TF00). 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 415 MPa (60.2 ksi) for C82100 TF00-AC, about 24% more; tensile strength follows at 655 MPa (95 ksi) vs 550 MPa (79.8 ksi). In exchange, C82100 TF00-AC is the more ductile: elongation 8% versus 6% for C82100-TF00, and C82100-TF00 is harder (200 HB vs 170 HB).
C82100-TF00Choose it when strength drives the design.
C82100 TF00-ACChoose it when the part is bent, formed or impact-loaded.
C82100-TF00 vs C82100 TF00-AC: 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.
