Copper Alloy C17300-A vs C17300-TF00
Copper Alloy · C17300 temper comparison
C17300-A and C17300-TF00 are two conditions of the same copper alloy grade, C17300: A (solution annealed) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C17300-TF00 is the stronger of the two: yield strength 1,035 MPa (150 ksi) against 220 MPa (31.9 ksi) for C17300-A, about 4.7 times as much; tensile strength follows at 1,210 MPa (175 ksi) vs 470 MPa (68.2 ksi). In exchange, C17300-A is the more ductile: elongation 40% versus 5% for C17300-TF00, and C17300-TF00 is harder (360 HB vs 110 HB). C17300-TF00 runs hotter in service (200°C vs 150°C continuous) and C17300-TF00 conducts electricity better (24 % IACS vs 18 % IACS). On the shop floor, C17300-TF00 welds better (25 vs 15 out of 100).
C17300-AChoose it when the part is bent, formed or impact-loaded.
C17300-TF00Choose it when strength drives the design, or when the part sees heat.
C17300-A vs C17300-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.

C17300-A vs C17300-TF00 — frequently asked
Is C17300-TF00 stronger than C17300-A?
Yes. C17300-TF00 has a typical yield strength of 1,035 MPa (150 ksi) against 220 MPa (31.9 ksi) for C17300-A — about 4.7 times as much. Tensile strength is 1,210 MPa (175 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, A or TF00?
A is the default C17300 condition in the FabDigit quote flow. 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.
Which is easier to machine, C17300-A or C17300-TF00?
C17300-TF00. Its machinability rates good (55/100) against fair (50/100) for C17300-A; for welding the order is C17300-TF00 first (poor, 25/100) then C17300-A (poor, 15/100).
