Copper Alloy C17510 vs C18000
Copper Alloy · grade comparison
Copper Alloy C17510 and C18000 are both copper alloy grades, both conductive cu alloy. C18000 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 170 MPa (24.7 ksi) for C17510, about 3.4 times as much; tensile strength follows at 690 MPa (100 ksi) vs 310 MPa (45 ksi). In exchange, C17510 is the more ductile: elongation 25% versus 12% for C18000, and C18000 is harder (200 HB vs 70 HB). C18000 runs hotter in service (400°C vs 200°C continuous) and C18000 conducts heat better (200 W/m·K vs 105 W/m·K). On the shop floor, C18000 machines more easily (fair vs poor), C17510 welds better (good vs fair), and C18000 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.
C18000Choose it when strength drives the design, or when the part sees heat.
C17510 vs C18000: 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.
