Copper Alloy C10200 vs C11400
Copper Alloy · grade comparison
Copper Alloy C10200 and C11400 are both copper alloy grades. C11400 is the stronger of the two: yield strength 310 MPa (45 ksi) against 69 MPa (10 ksi) for C10200, about 4.5 times as much; tensile strength follows at 345 MPa (50 ksi) vs 221 MPa (32.1 ksi). In exchange, C10200 is the more ductile: elongation 45% versus 6% for C11400, and C11400 is harder (90 HB vs 45 HB). C10200 runs hotter in service (250°C vs 180°C continuous). On the shop floor, C10200 welds better (good vs poor).
C10200Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C11400Choose it when strength drives the design.
C10200 vs C11400: 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.

C10200 vs C11400 — frequently asked
Is C11400 stronger than C10200?
Yes. C11400 has a typical yield strength of 310 MPa (45 ksi) against 69 MPa (10 ksi) for C10200 — about 4.5 times as much. Tensile strength is 345 MPa (50 ksi) vs 221 MPa (32.1 ksi).
Which is cheaper, C10200 or C11400?
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 welds better, C10200 or C11400?
C10200. Its weldability rates good (65/100) against poor (30/100) for C11400.
