Copper Alloy C10100 vs CuAg0.04P
Copper Alloy · grade comparison
Copper Alloy C10100 and CuAg0.04P are both copper alloy grades. CuAg0.04P is the stronger of the two: yield strength 200 MPa (29 ksi) against 69 MPa (10 ksi) for C10100, about 190% more; tensile strength follows at 265 MPa (38.4 ksi) vs 235 MPa (34.1 ksi). In exchange, C10100 is the more ductile: elongation 45% versus 18% for CuAg0.04P, and CuAg0.04P is harder (85 HB vs 45 HB). CuAg0.04P runs hotter in service (250°C vs 200°C continuous). On the shop floor, CuAg0.04P machines more easily (28 vs 18 out of 100), CuAg0.04P welds better (excellent vs very good), and CuAg0.04P sits in a lower cost tier (high, $$$$) than C10100 (specialty, $$$$$).
C10100Choose it when the part is bent, formed or impact-loaded.
CuAg0.04PChoose it when strength drives the design, or when the part sees heat.
C10100 vs CuAg0.04P: 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.

C10100 vs CuAg0.04P — frequently asked
Is CuAg0.04P stronger than C10100?
Yes. CuAg0.04P has a typical yield strength of 200 MPa (29 ksi) against 69 MPa (10 ksi) for C10100 — about 190% more. Tensile strength is 265 MPa (38.4 ksi) vs 235 MPa (34.1 ksi).
Which is cheaper, C10100 or CuAg0.04P?
CuAg0.04P is the lower-cost material: it sits in the high tier ($$$$) while C10100 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, C10100 or CuAg0.04P?
CuAg0.04P, by a small margin. Both rate poor for machinability — 28/100 against 18/100 for C10100; for welding the order is CuAg0.04P first (excellent, 85/100) then C10100 (very good, 70/100).
