Copper Alloy C17510 vs C70250
Copper Alloy · grade comparison
Copper Alloy C17510 and C70250 are both copper alloy grades. C70250 is the stronger of the two: yield strength 640 MPa (92.8 ksi) against 170 MPa (24.7 ksi) for C17510, about 3.8 times as much; tensile strength follows at 700 MPa (102 ksi) vs 310 MPa (45 ksi). In exchange, C17510 is the more ductile: elongation 25% versus 9% for C70250, and C70250 is harder (200 HV vs 75 HV). C70250 conducts heat better (155 W/m·K vs 105 W/m·K). On the shop floor, C70250 machines more easily (fair vs poor), C17510 welds better (good vs fair), and C70250 sits in a lower cost tier (high, $$$$) than C17510 (specialty, $$$$$).
C17510Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C70250Choose it when strength drives the design, or when the part is machined in volume.
C17510 vs C70250: 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.
