    Factors Affecting Resistivity of Copper Wire

    Copper content. The pureness of common copper wire is higher that 99%, while even higher if made in oxygen-free copper. Impurity is harmful to safety of large current load, the higher impurity, the higher resistivity, in other words, higher pureness is better.
