Copper Alloy C52100 vs C53400

Copper Alloy · grade comparison

Copper Alloy C52100 and C53400 are both copper alloy grades. C52100 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 450 MPa (65.3 ksi) for C53400, about 30% more; tensile strength follows at 660 MPa (95.7 ksi) vs 490 MPa (71.1 ksi). C52100 is the more ductile: elongation 10% versus 6% for C53400, and C52100 is harder (170 HB vs 150 HB). C52100 runs hotter in service (200°C vs 150°C continuous) and C53400 conducts heat better (84 W/m·K vs 62 W/m·K). On the shop floor, C53400 machines more easily (very good vs poor), C52100 welds better (fair vs poor), and C53400 sits in a lower cost tier (high, $$$$) than C52100 (specialty, $$$$$).

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

C53400Choose it when the part is machined in volume, or when cost is the deciding factor.
