Copper Alloy C22600 vs C52100

Copper Alloy · grade comparison

Copper Alloy C22600 and C52100 are both copper alloy grades. C52100 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 330 MPa (47.9 ksi) for C22600, about 77% more; tensile strength follows at 660 MPa (95.7 ksi) vs 400 MPa (58 ksi). In exchange, C22600 is the more ductile: elongation 12% versus 10% for C52100, and C52100 is harder (170 HB vs 105 HB). C22600 is stiffer (117 GPa vs 110 GPa) and C22600 conducts heat better (172 W/m·K vs 62 W/m·K). On the shop floor, C22600 welds better (good vs fair) and C22600 sits in a lower cost tier (high, $$$$) than C52100 (specialty, $$$$$).

C22600Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

C52100Choose it when strength drives the design.
