Copper Alloy C10100 vs Cu-ETP1
Copper Alloy · grade comparison
Copper Alloy C10100 and Cu-ETP1 are both copper alloy grades. C10100 is the stronger of the two: tensile strength 235 MPa (34.1 ksi) against 220 MPa (31.9 ksi) for Cu-ETP1, about 7% more. C10100 is the more ductile: elongation 45% versus 40% for Cu-ETP1. On the shop floor, Cu-ETP1 machines more easily (30 vs 18 out of 100), C10100 welds better (very good vs fair), and Cu-ETP1 sits in a lower cost tier (high, $$$$) than C10100 (specialty, $$$$$).
C10100Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Cu-ETP1Choose it when the part is machined in volume, or when cost is the deciding factor.
C10100 vs Cu-ETP1: 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 Cu-ETP1 — frequently asked
Is C10100 stronger than Cu-ETP1?
Yes. C10100 has a typical tensile strength of 235 MPa (34.1 ksi) against 220 MPa (31.9 ksi) for Cu-ETP1 — about 7% more.
Which is cheaper, C10100 or Cu-ETP1?
Cu-ETP1 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 Cu-ETP1?
Cu-ETP1, by a small margin. Both rate poor for machinability — 30/100 against 18/100 for C10100; for welding the order is C10100 first (very good, 70/100) then Cu-ETP1 (fair, 50/100).
