Copper Alloy Cu-ETP1 vs CuAg0.10(OF)

Copper Alloy · grade comparison

Copper Alloy Cu-ETP1 and CuAg0.10(OF) are both copper alloy grades. Both yield at about 70 MPa — strength does not separate them. CuAg0.10(OF) is the more ductile: elongation 45% versus 40% for Cu-ETP1. CuAg0.10(OF) runs hotter in service (350°C vs 200°C continuous). On the shop floor, Cu-ETP1 machines more easily (30 vs 20 out of 100) and CuAg0.10(OF) welds better (good vs fair).

Cu-ETP1Choose it when the part is machined in volume.

CuAg0.10(OF)Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Cu-ETP1 vs CuAg0.10(OF) — frequently asked

What is the difference between Cu-ETP1 and CuAg0.10(OF)?

Copper Alloy Cu-ETP1 and CuAg0.10(OF) are both copper alloy grades. Both yield at about 70 MPa — strength does not separate them. CuAg0.10(OF) is the more ductile: elongation 45% versus 40% for Cu-ETP1.

Which is cheaper, Cu-ETP1 or CuAg0.10(OF)?

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 CuAg0.10(OF)?

Cu-ETP1, by a small margin. Both rate poor for machinability — 30/100 against 20/100 for CuAg0.10(OF); for welding the order is CuAg0.10(OF) first (good, 65/100) then Cu-ETP1 (fair, 50/100).
