We present results of calculations of the electrical and thermal conductivity and the phonon-drag thermopower in pure Al including a realistic Fermi surface and multiple-plane-wave electron-phonon matrix elements. Scattering times to electrical and thermal conductivity are computed as a function of position on the Fermi surface at various temperatures. Large anisotropies are observed, particularly at low temperatures. Comparison of our results for the electrical resistivity and the phonon-drag thermopower with previous one-plane-wave calculations show considerable differences and the agreement with experiment is significantly improved.
