Copper Alloy C93200 vs C95400
Copper Alloy · grade comparison
Copper Alloy C93200 and C95400 are both copper alloy grades. C95400 is the stronger of the two: yield strength 241 MPa (35 ksi) against 125 MPa (18.1 ksi) for C93200, about 93% more; tensile strength follows at 586 MPa (85 ksi) vs 240 MPa (34.8 ksi). In exchange, C93200 is the more ductile: elongation 20% versus 12% for C95400, and C95400 is harder (170 HB vs 65 HB). C95400 is lighter (7.45 g/cm³ vs 8.93 g/cm³ for C93200) and C95400 is stiffer (110 GPa vs 100 GPa). On the shop floor, C93200 machines more easily (very good vs fair), C95400 welds better (good vs poor), and C93200 sits in a lower cost tier (premium, $$$) than C95400 (specialty, $$$$$).
C93200Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
C95400Choose it when strength drives the design, or when weight is the constraint.
C93200 vs C95400: 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.
