Copper Alloy C84800 vs CC330G

Copper Alloy · grade comparison

Copper Alloy C84800 and CC330G are both copper alloy grades. CC330G 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 500 MPa (72.5 ksi) vs 262 MPa (38 ksi). In exchange, C84800 is the more ductile: elongation 35% versus 25% for CC330G, and CC330G is harder (110 HB vs 55 HB). CC330G is lighter (7.6 g/cm³ vs 8.55 g/cm³ for C84800) and CC330G is stiffer (112 GPa vs 86 GPa). On the shop floor, C84800 machines more easily (excellent vs fair), CC330G welds better (very good vs poor), and CC330G 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.

CC330GChoose it when strength drives the design, or when weight is the constraint.
