Copper Alloy C84800 vs C95300

Copper Alloy · grade comparison

Copper Alloy C84800 and C95300 are both copper alloy grades. C95300 is the stronger of the two: yield strength 170 MPa (24.7 ksi) against 124 MPa (18 ksi) for C84800, about 37% more; tensile strength follows at 450 MPa (65.3 ksi) vs 262 MPa (38 ksi). In exchange, C84800 is the more ductile: elongation 35% versus 25% for C95300, and C95300 is harder (110 HB vs 55 HB). C95300 is lighter (7.53 g/cm³ vs 8.55 g/cm³ for C84800) and C95300 is stiffer (110 GPa vs 86 GPa). On the shop floor, C84800 machines more easily (excellent vs fair), C95300 welds better (very good vs poor), and C95300 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.

C95300Choose it when strength drives the design, or when weight is the constraint.
