Copper Alloy C10100 vs CuAg0.10

Copper Alloy · grade comparison

Copper Alloy C10100 and CuAg0.10 are both copper alloy grades. CuAg0.10 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 275 MPa (39.9 ksi) vs 235 MPa (34.1 ksi). In exchange, C10100 is the more ductile: elongation 45% versus 15% for CuAg0.10, and CuAg0.10 is harder (76 HB vs 45 HB). CuAg0.10 runs hotter in service (250°C vs 200°C continuous). On the shop floor, C10100 welds better (very good vs fair) and CuAg0.10 sits in a lower cost tier (high, $$$$) than C10100 (specialty, $$$$$).

C10100Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

CuAg0.10Choose it when strength drives the design, or when the part sees heat.

C10100 vs CuAg0.10 — frequently asked

Is CuAg0.10 stronger than C10100?

Yes. CuAg0.10 has a typical yield strength of 200 MPa (29 ksi) against 69 MPa (10 ksi) for C10100 — about 190% more. Tensile strength is 275 MPa (39.9 ksi) vs 235 MPa (34.1 ksi).

Which is cheaper, C10100 or CuAg0.10?

CuAg0.10 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 CuAg0.10?

CuAg0.10, by a small margin. Both rate poor for machinability — 25/100 against 18/100 for C10100; for welding the order is C10100 first (very good, 70/100) then CuAg0.10 (fair, 40/100).
