Used for the manufacturing of wires, sheets, plates, sections and coils for electrical usings, it is the most usual quality. It is sometimes called "electrolytic copper".
It is sensitive to heating in a reducing atmosphere, that requires some restrictions during the heat treatments and welding, especially with a welding torch.
