Copper Alloy C10200 vs C11300
Copper Alloy · grade comparison
Copper Alloy C10200 and C11300 are both copper alloy grades. C11300 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 C11300, and C11300 is harder (100 HB vs 45 HB). C10200 runs hotter in service (250°C vs 200°C continuous). On the shop floor, C11300 machines more easily (32 vs 22 out of 100) and C10200 welds better (good vs fair).
C10200Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C11300Choose it when strength drives the design, or when the part is machined in volume.
C10200 vs C11300: 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 C11300 — frequently asked
Is C11300 stronger than C10200?
Yes. C11300 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 C11300?
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, C10200 or C11300?
C11300, by a small margin. Both rate poor for machinability — 32/100 against 22/100 for C10200; for welding the order is C10200 first (good, 65/100) then C11300 (fair, 35/100).
