Copper Cu-ETP (CW004A)
Cu-ETP is oxygen-containing copper with high electrical conductivity. It is the classic material for current-carrying components, easy to soft solder but only conditionally weldable and hard solderable. Under EN it is designated CW004A, the earlier designation is E-Cu57, earlier material number 2.0060.
We supply Cu-ETP as round bars, flat bars and hexagonal bars ex stock. Cut to your dimensions, no minimum order.
