Copper Alloy C12200 vs C19210
Copper Alloy · grade comparison
Copper Alloy C12200 and C19210 are both copper alloy grades. C19210 is the stronger of the two: yield strength 345 MPa (50 ksi) against 76 MPa (11 ksi) for C12200, about 4.5 times as much; tensile strength follows at 370 MPa (53.7 ksi) vs 235 MPa (34.1 ksi). In exchange, C12200 is the more ductile: elongation 45% versus 5% for C19210. On the shop floor, C12200 welds better (excellent vs fair).
C12200Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C19210Choose it when strength drives the design.
C12200 vs C19210: 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 C19210 — frequently asked
Is C19210 stronger than C12200?
Yes. C19210 has a typical yield strength of 345 MPa (50 ksi) against 76 MPa (11 ksi) for C12200 — about 4.5 times as much. Tensile strength is 370 MPa (53.7 ksi) vs 235 MPa (34.1 ksi).
Which is cheaper, C12200 or C19210?
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 C19210?
C19210, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for C12200; for welding the order is C12200 first (excellent, 85/100) then C19210 (fair, 45/100).
