Copper Alloy C50500 vs C52100

Copper Alloy · grade comparison

Copper Alloy C50500 and C52100 are both copper alloy grades. C52100 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 345 MPa (50 ksi) for C50500, about 70% more; tensile strength follows at 660 MPa (95.7 ksi) vs 380 MPa (55.1 ksi). C52100 is the more ductile: elongation 10% versus 6% for C50500, and C52100 is harder (170 HB vs 110 HB). C50500 is stiffer (117 GPa vs 110 GPa) and C52100 runs hotter in service (200°C vs 175°C continuous). On the shop floor, C50500 welds better (good vs fair) and C50500 sits in a lower cost tier (high, $$$$) than C52100 (specialty, $$$$$).

C50500Choose 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.

C50500 vs C52100 — frequently asked

Is C52100 stronger than C50500?

Yes. C52100 has a typical yield strength of 585 MPa (84.8 ksi) against 345 MPa (50 ksi) for C50500 — about 70% more. Tensile strength is 660 MPa (95.7 ksi) vs 380 MPa (55.1 ksi).

Which is cheaper, C50500 or C52100?

C50500 is the lower-cost material: it sits in the high tier ($$$$) while C52100 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, C50500 or C52100?

C52100, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for C50500; for welding the order is C50500 first (good, 55/100) then C52100 (fair, 40/100).
