Copper Alloy C12200 vs C19500
Copper Alloy · grade comparison
Copper Alloy C12200 and C19500 are both copper alloy grades. C19500 is the stronger of the two: yield strength 517 MPa (75 ksi) against 76 MPa (11 ksi) for C12200, about 6.8 times as much; tensile strength follows at 552 MPa (80.1 ksi) vs 235 MPa (34.1 ksi). In exchange, C12200 is the more ductile: elongation 45% versus 5% for C19500. C19500 is stiffer (131 GPa vs 117 GPa) and C12200 conducts heat better (339 W/m·K vs 200 W/m·K). On the shop floor, C19500 machines more easily (30 vs 20 out of 100) and C12200 welds better (excellent vs fair).
C12200Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C19500Choose it when strength drives the design, or when the part is machined in volume.
C12200 vs C19500: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

C12200 vs C19500 — frequently asked
Is C19500 stronger than C12200?
Yes. C19500 has a typical yield strength of 517 MPa (75 ksi) against 76 MPa (11 ksi) for C12200 — about 6.8 times as much. Tensile strength is 552 MPa (80.1 ksi) vs 235 MPa (34.1 ksi).
Which is cheaper, C12200 or C19500?
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 C19500?
C19500, by a small margin. Both rate poor for machinability — 30/100 against 20/100 for C12200; for welding the order is C12200 first (excellent, 85/100) then C19500 (fair, 40/100).
