Copper Alloy C12200 vs C19010

Copper Alloy · grade comparison

Copper Alloy C12200 and C19010 are both copper alloy grades. C19010 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 76 MPa (11 ksi) for C12200, about 6.3 times as much; tensile strength follows at 520 MPa (75.4 ksi) vs 235 MPa (34.1 ksi). In exchange, C12200 is the more ductile: elongation 45% versus 8% for C19010. C19010 is stiffer (131 GPa vs 117 GPa) and C12200 conducts heat better (339 W/m·K vs 230 W/m·K). On the shop floor, C19010 machines more easily (fair vs poor) and C12200 welds better (excellent vs fair).

C12200Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

C19010Choose it when strength drives the design, or when the part is machined in volume.

C12200 vs C19010 — frequently asked

Is C19010 stronger than C12200?

Yes. C19010 has a typical yield strength of 480 MPa (69.6 ksi) against 76 MPa (11 ksi) for C12200 — about 6.3 times as much. Tensile strength is 520 MPa (75.4 ksi) vs 235 MPa (34.1 ksi).

Which is cheaper, C12200 or C19010?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, C12200 or C19010?

C19010. Its machinability rates fair (40/100) against poor (20/100) for C12200; for welding the order is C12200 first (excellent, 85/100) then C19010 (fair, 45/100).
