The ionic and electronic properties of liquid Al and Ga metals and Al 1−x Ga x alloys have been investigated self-consistently. Partial structure factors have been calculated from the solution of the Ornstein-Zernike equation with the hybridized mean spherical approximation closure, and the transferable electron-ion potential of Fiolhais et al. has been used as the input pseudopotential. Two different formulas are used in the electrical resistivity calculation, namely, the Faber-Ziman formula and the modified Ziman's formula suggested by Ferraz-March. The results are compared with each other and experimental values.
