Copper Alloy C84800 vs CC334G

Copper Alloy · grade comparison

Copper Alloy C84800 and CC334G are both copper alloy grades. CC334G is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 124 MPa (18 ksi) for C84800, about 3.6 times as much; tensile strength follows at 710 MPa (103 ksi) vs 262 MPa (38 ksi). In exchange, C84800 is the more ductile: elongation 35% versus 6% for CC334G, and CC334G is harder (250 HB vs 55 HB). CC334G is lighter (7.45 g/cm³ vs 8.55 g/cm³ for C84800) and CC334G is stiffer (122 GPa vs 86 GPa). On the shop floor, C84800 machines more easily (excellent vs poor), CC334G welds better (fair vs poor), and CC334G 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.

CC334GChoose it when strength drives the design, or when weight is the constraint.
