Copper Alloy C89836 vs C95500
Copper Alloy · grade comparison
Copper Alloy C89836 and C95500 are both copper alloy grades. C95500 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 115 MPa (16.7 ksi) for C89836, about 161% more; tensile strength follows at 700 MPa (102 ksi) vs 250 MPa (36.3 ksi). In exchange, C89836 is the more ductile: elongation 22% versus 8% for C95500, and C95500 is harder (192 HB vs 60 HB). C95500 is lighter (7.53 g/cm³ vs 8.6 g/cm³ for C89836) and C95500 is stiffer (110 GPa vs 96 GPa). On the shop floor, C89836 machines more easily (very good vs fair), C95500 welds better (good vs poor), and C89836 sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).
C89836Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
C95500Choose it when strength drives the design, or when weight is the constraint.
C89836 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.
