Copper Alloy C95500 vs CC330G

Copper Alloy · grade comparison

Copper Alloy C95500 and CC330G are both copper alloy grades. C95500 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 200 MPa (29 ksi) for CC330G, about 50% more; tensile strength follows at 700 MPa (102 ksi) vs 500 MPa (72.5 ksi). In exchange, CC330G is the more ductile: elongation 25% versus 8% for C95500, and C95500 is harder (192 HB vs 110 HB). CC330G conducts heat better (59 W/m·K vs 42 W/m·K). On the shop floor, CC330G welds better (very good vs good) and CC330G sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).
