Copper Alloy Cu-ETP1 vs CuAg0.10P
Copper Alloy · grade comparison
Copper Alloy Cu-ETP1 and CuAg0.10P are both copper alloy grades. CuAg0.10P is the stronger of the two: yield strength 200 MPa (29 ksi) against 70 MPa (10.2 ksi) for Cu-ETP1, about 186% more; tensile strength follows at 265 MPa (38.4 ksi) vs 220 MPa (31.9 ksi). In exchange, Cu-ETP1 is the more ductile: elongation 40% versus 25% for CuAg0.10P, and CuAg0.10P is harder (68 HB vs 45 HB). CuAg0.10P runs hotter in service (300°C vs 200°C continuous). On the shop floor, CuAg0.10P welds better (excellent vs fair).
Cu-ETP1Choose it when the part is bent, formed or impact-loaded.
CuAg0.10PChoose it when strength drives the design, or when the part sees heat.
Cu-ETP1 vs CuAg0.10P: 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.

Cu-ETP1 vs CuAg0.10P — frequently asked
Is CuAg0.10P stronger than Cu-ETP1?
Yes. CuAg0.10P has a typical yield strength of 200 MPa (29 ksi) against 70 MPa (10.2 ksi) for Cu-ETP1 — about 186% more. Tensile strength is 265 MPa (38.4 ksi) vs 220 MPa (31.9 ksi).
Which is cheaper, Cu-ETP1 or CuAg0.10P?
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, Cu-ETP1 or CuAg0.10P?
Cu-ETP1, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for CuAg0.10P; for welding the order is CuAg0.10P first (excellent, 90/100) then Cu-ETP1 (fair, 50/100).
