Copper Alloy C11000 vs CuAg0.04
Copper Alloy · grade comparison
Copper Alloy C11000 and CuAg0.04 are both copper alloy grades. CuAg0.04 is the stronger of the two: yield strength 310 MPa (45 ksi) against 69 MPa (10 ksi) for C11000, about 4.5 times as much; tensile strength follows at 360 MPa (52.2 ksi) vs 221 MPa (32.1 ksi). In exchange, C11000 is the more ductile: elongation 45% versus 8% for CuAg0.04, and CuAg0.04 is harder (105 HB vs 45 HB). CuAg0.04 is stiffer (125 GPa vs 117 GPa) and C11000 runs hotter in service (250°C vs 220°C continuous).
C11000Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
CuAg0.04Choose it when strength drives the design.
C11000 vs CuAg0.04: 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 CuAg0.04 — frequently asked
Is CuAg0.04 stronger than C11000?
Yes. CuAg0.04 has a typical yield strength of 310 MPa (45 ksi) against 69 MPa (10 ksi) for C11000 — about 4.5 times as much. Tensile strength is 360 MPa (52.2 ksi) vs 221 MPa (32.1 ksi).
Which is cheaper, C11000 or CuAg0.04?
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.
When should I choose C11000 over CuAg0.04?
Pick C11000 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick CuAg0.04 when strength drives the design.
