Copper Alloy C84800 vs ZCuAl8Mn13Fe3Ni2
Copper Alloy · grade comparison
Copper Alloy C84800 and ZCuAl8Mn13Fe3Ni2 are both copper alloy grades. ZCuAl8Mn13Fe3Ni2 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 124 MPa (18 ksi) for C84800, about 158% more; tensile strength follows at 690 MPa (100 ksi) vs 262 MPa (38 ksi). In exchange, C84800 is the more ductile: elongation 35% versus 22% for ZCuAl8Mn13Fe3Ni2, and ZCuAl8Mn13Fe3Ni2 is harder (180 HB vs 55 HB). ZCuAl8Mn13Fe3Ni2 is lighter (7.53 g/cm³ vs 8.55 g/cm³ for C84800) and ZCuAl8Mn13Fe3Ni2 is stiffer (120 GPa vs 86 GPa). On the shop floor, C84800 machines more easily (excellent vs fair), ZCuAl8Mn13Fe3Ni2 welds better (good vs poor), and ZCuAl8Mn13Fe3Ni2 sits in a lower cost tier (high, $$$$) than C84800 (specialty, $$$$$).
C84800Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
ZCuAl8Mn13Fe3Ni2Choose it when strength drives the design, or when weight is the constraint.
C84800 vs ZCuAl8Mn13Fe3Ni2: 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.
