In the past, several experiments were made to investigate the effect of metallic impurities on the electrical conductivity of aluminium. But it has not almost studied in details on the range of less impurites than 0.3%. and aluminium wire for conductor cable of another country are differ in the impurity content of Fe and Si, although they have more Fe than Si
So that, adding a small amount of Fe and Si, which entered whenever virgin aluminium was produced, to the high purity aluminium (99.987%), their effects were examined.
Fe. Si, were added to the amounts of 0.4% at intervals of 0.04%, then the conductivities of Al-corner in the Al-Fe-Si ternary systems have been measured.
As the result, electrical conductivity of aluminium varies on these range of two demensions, relating to working-degree and heat treatment, as follows-.
