Copper Alloy C95500 vs C95600

Copper Alloy · grade comparison

Copper Alloy C95500 and C95600 are both copper alloy grades. C95500 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 193 MPa (28 ksi) for C95600, about 55% more; tensile strength follows at 700 MPa (102 ksi) vs 414 MPa (60 ksi). In exchange, C95600 is the more ductile: elongation 18% versus 8% for C95500, and C95500 is harder (192 HB vs 140 HB). C95600 is stiffer (117 GPa vs 110 GPa) and C95500 conducts electricity better (8.5 % IACS vs 7.5 % IACS). On the shop floor, C95600 machines more easily (good vs fair) and C95600 sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).
