Abstract

The Cu consumption by the chinese cable industry amounted to 3.54 million tons in 2006, taking over 70 % of the total Cu consumption in China in that year. At present, making Cu rod directly from recovered scrap Cu and saving Cu with Al have become topics of general interests in the chinese cable industry. The quality of the Cu conductors in the industry is declining, resulting in sharp decrease in the rate of qualified wire and cable products. More and more Cu wires are drawn from the rods made directly from scrap Cu. The manufacturers know well some of the wires or rods are unqualified products though, they continue to use or produce products,not complying with standards in order to make profits. Now the consumption of Cu-clad-aluminum and Cu-clad-steel is growing gradually. In 2006, the consumption of Cu-clad-aluminum in China amounted to ca. 50 000 tons. But in some applications, neither the common understanding between buyer and supplier nor the results of feasibility study are achieved in the product orientation and technical/economic feasibility in terms of saving Cu with Al. This paper presents the status-quo, problems arisen and suggestions in terms of making Cu rod directly from recovered scrap Cu and saving Cu with Al, in a view to promote these two topics of general interests to go toward a virtuous circle.
