Copper Alloy C50100 vs C52100

Copper Alloy · grade comparison

Copper Alloy C50100 and C52100 are both copper alloy grades. C52100 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 350 MPa (50.8 ksi) for C50100, about 67% more; tensile strength follows at 660 MPa (95.7 ksi) vs 390 MPa (56.6 ksi). C52100 is the more ductile: elongation 10% versus 8% for C50100, and C52100 is harder (170 HB vs 115 HB). C50100 is stiffer (117 GPa vs 110 GPa) and C50100 conducts heat better (210 W/m·K vs 62 W/m·K). On the shop floor, C50100 welds better (good vs fair) and C50100 sits in a lower cost tier (high, $$$$) than C52100 (specialty, $$$$$).

C50100Choose it when it will be welded, or when cost is the deciding factor.

C52100Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
