The electrical resistivity of a series of dilute polycrystalline Cu(Al) alloys has been investigated in the temperature range 4.2 - 300 K. The phonon part of the resistivity at low temperature varies as where 4 < n < 5. The temperature corresponding to the maxima of the deviations from Matthiessen's rule obeys the Kagan - Zhernov law, i.e. . At high temperatures the slope of depends on the impurity concentration and changes sign from negative to positive.
