C80100 vs Cu-ETP1 — frequently asked

Is Cu-ETP1 stronger than C80100?

Yes. Cu-ETP1 has a typical yield strength of 70 MPa (10.2 ksi) against 62 MPa (8.99 ksi) for C80100 — about 13% more. Tensile strength is 220 MPa (31.9 ksi) vs 172 MPa (24.9 ksi).

Which is cheaper, C80100 or Cu-ETP1?

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, C80100 or Cu-ETP1?

Cu-ETP1, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for C80100; for welding the order is C80100 first (good, 55/100) then Cu-ETP1 (fair, 50/100).
