Copper Alloy C84800 vs ZCuAl10Fe3

Copper Alloy · grade comparison

Copper Alloy C84800 and ZCuAl10Fe3 are both copper alloy grades. ZCuAl10Fe3 is the stronger of the two: yield strength 200 MPa (29 ksi) against 124 MPa (18 ksi) for C84800, about 61% more; tensile strength follows at 540 MPa (78.3 ksi) vs 262 MPa (38 ksi). In exchange, C84800 is the more ductile: elongation 35% versus 20% for ZCuAl10Fe3, and ZCuAl10Fe3 is harder (120 HB vs 55 HB). ZCuAl10Fe3 is lighter (7.5 g/cm³ vs 8.55 g/cm³ for C84800) and ZCuAl10Fe3 is stiffer (110 GPa vs 86 GPa). On the shop floor, C84800 machines more easily (excellent vs fair), ZCuAl10Fe3 welds better (good vs poor), and ZCuAl10Fe3 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.

ZCuAl10Fe3Choose it when strength drives the design, or when weight is the constraint.
