Copper Alloy C17450 vs C17510
Copper Alloy · grade comparison
Copper Alloy C17450 and C17510 are both copper alloy grades. C17450 is the stronger of the two: yield strength 600 MPa (87 ksi) against 170 MPa (24.7 ksi) for C17510, about 3.5 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 12% for C17450, and C17450 is harder (200 HB vs 70 HB). C17450 is stiffer (138 GPa vs 131 GPa) and C17450 conducts heat better (210 W/m·K vs 105 W/m·K). On the shop floor, C17450 machines more easily (fair vs poor) and C17450 sits in a lower cost tier (high, $$$$) than C17510 (specialty, $$$$$).
C17450Choose it when strength drives the design, or when the part is machined in volume.
C17510Choose it when the part is bent, formed or impact-loaded.
C17450 vs C17510: 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.
