Copper Alloy C86100 vs C95500
Copper Alloy · grade comparison
Copper Alloy C86100 and C95500 are both copper alloy grades. C86100 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 300 MPa (43.5 ksi) for C95500, about 38% more; tensile strength follows at 820 MPa (119 ksi) vs 700 MPa (102 ksi). C86100 is the more ductile: elongation 20% versus 8% for C95500, and C86100 is harder (225 HB vs 192 HB). C95500 is stiffer (110 GPa vs 103 GPa) and C95500 runs hotter in service (300°C vs 200°C continuous). On the shop floor, C95500 machines more easily (fair vs poor), C95500 welds better (good vs poor), and C86100 sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).
C86100Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C95500Choose it when the part sees heat, or when the part is machined in volume.
C86100 vs C95500: 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.
