Copper Alloy C11000 vs C80100
Copper Alloy · grade comparison
Copper Alloy C11000 and C80100 are both copper alloy grades. C11000 is the stronger of the two: yield strength 69 MPa (10 ksi) against 62 MPa (8.99 ksi) for C80100, about 11% more; tensile strength follows at 221 MPa (32.1 ksi) vs 172 MPa (24.9 ksi). C11000 is the more ductile: elongation 45% versus 40% for C80100. C11000 runs hotter in service (250°C vs 200°C continuous). On the shop floor, C80100 welds better (good vs fair).
C11000Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C80100Choose it when it will be welded.
C11000 vs C80100: 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.

C11000 vs C80100 — frequently asked
Is C11000 stronger than C80100?
Yes. C11000 has a typical yield strength of 69 MPa (10 ksi) against 62 MPa (8.99 ksi) for C80100 — about 11% more. Tensile strength is 221 MPa (32.1 ksi) vs 172 MPa (24.9 ksi).
Which is cheaper, C11000 or C80100?
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, C11000 or C80100?
C80100. Its weldability rates good (55/100) against fair (35/100) for C11000.
