Copper Alloy C19000-HR01 vs C19000-TF00
Copper Alloy · C19000 temper comparison
C19000-HR01 and C19000-TF00 are two conditions of the same copper alloy grade, C19000: HR01 (quarter hard, cold rolled and stress relieved) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C19000-HR01 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 310 MPa (45 ksi) for C19000-TF00, about 23% more; tensile strength follows at 425 MPa (61.6 ksi) vs 400 MPa (58 ksi). In exchange, C19000-TF00 is the more ductile: elongation 18% versus 13% for C19000-HR01, and C19000-HR01 is harder (135 HV vs 125 HV). C19000-TF00 runs hotter in service (250°C vs 200°C continuous).
C19000-HR01Choose it when strength drives the design.
C19000-TF00Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C19000-HR01 vs C19000-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.

C19000-HR01 vs C19000-TF00 — frequently asked
Is C19000-HR01 stronger than C19000-TF00?
Yes. C19000-HR01 has a typical yield strength of 380 MPa (55.1 ksi) against 310 MPa (45 ksi) for C19000-TF00 — about 23% more. Tensile strength is 425 MPa (61.6 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, HR01 or TF00?
HR02 is the default C19000 condition in the FabDigit quote flow (neither HR01 nor TF00). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose C19000-HR01 over C19000-TF00?
Pick C19000-HR01 when strength drives the design. Pick C19000-TF00 when the part is bent, formed or impact-loaded, or when the part sees heat.
