Demands on copper by the electrical equipment industry and the development situation of the copper substitutes

According to the statistics of the internationally concerned agency, these days the annual copper concentrates use volume globally is basically around 16.00-18.00 million tons. The speculation on the international copper futures market made the copper price keep on soaring since 2004, which soared irrationally when it came to 2006. With the constant increase of the copper price, the price difference of copper and aluminum, the major conductors for electric wires and cables, expands further. The cost of copper application increases straightly. These days, the cost of copper has accounted for more than 80% of the material cost. The issue of copper substitute has become a common concern.
