For the wire and cable industry, the most obvious material alternative is to use aluminum conductors instead of copper conductors. In the copper, aluminum cable relative cost, you need to consider the price, weight and conductivity and other factors, in order to draw the aluminum conductor is the real cost-saving answer. Copper is heavier than aluminum. The specific gravity of copper is 8.9g.cm3, the specific gravity of aluminum is 2.7g / cm3, that is to say, the weight of copper conductor is...
