The influence of additions fo 2, 6, and 8 wt. % Ag on the electrical resistivity of the Cu-5 wt. %Al alloy was studied by the four-probe d.c. method and an automated recorder system. The results indicated that the electrical resistivity of the alloy increases with silver concentration and that the inflexions on the curves of electrical resistivity changes with temperature may be ascribed to silver solubilization on the Cu-Al matrix. It was also observed that the sample heating rate may change the shape of the curve recorded.
