Copper Alloy C17510-A vs C17510-TH04
Copper Alloy · C17510 temper comparison
C17510-A and C17510-TH04 are two conditions of the same copper alloy grade, C17510: A (solution annealed) versus TH04 (TD04 and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C17510-TH04 is the stronger of the two: yield strength 760 MPa (110 ksi) against 170 MPa (24.7 ksi) for C17510-A, about 4.5 times as much; tensile strength follows at 830 MPa (120 ksi) vs 310 MPa (45 ksi). In exchange, C17510-A is the more ductile: elongation 25% versus 8% for C17510-TH04, and C17510-TH04 is harder (250 HB vs 70 HB). C17510-TH04 is stiffer (138 GPa vs 131 GPa) and C17510-TH04 runs hotter in service (340°C vs 200°C continuous). On the shop floor, C17510-TH04 machines more easily (fair vs poor).
C17510-AChoose it when the part is bent, formed or impact-loaded.
C17510-TH04Choose it when strength drives the design, or when the part sees heat.
C17510-A vs C17510-TH04: 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.

C17510-A vs C17510-TH04 — frequently asked
Is C17510-TH04 stronger than C17510-A?
Yes. C17510-TH04 has a typical yield strength of 760 MPa (110 ksi) against 170 MPa (24.7 ksi) for C17510-A — about 4.5 times as much. Tensile strength is 830 MPa (120 ksi) vs 310 MPa (45 ksi).
Which condition does FabDigit quote by default, A or TH04?
A is the default C17510 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, C17510-A or C17510-TH04?
C17510-TH04. Its machinability rates fair (50/100) against poor (25/100) for C17510-A; for welding the order is C17510-A first (good, 58/100) then C17510-TH04 (fair, 50/100).
