Refined copper is obtained by electrolytic refining, electrolytic extraction, chemical refining or fire refining. Other refined copper (containing at least 97.5 % by weight of copper) is normally produced by alloying refined copper with one or more other elements up to the maximum content limits as shown in the foregoing table. In practical application, it applies to refinery shapes that are directly consumed without further refining. Refined copper is cast into ingots or ingot-bars for re-melting or into wire bars, slabs for rolling, billets and similar forms for rolling, extruding, drawing or forging into plates, sheets, strips, wire, tubes and other semi-fabricates.
