Abstract: The electric and thermal conductivity, heat capacity, and thermal diffusivity of thin Ni$_{87.8}$Cr$_{9.3}$W$_{2.9}$ alloy ribbons have been measured. It is established that samples with a cubic texture possess better conducting properties than the nontextured ribbons. The electron and phonon components of thermal conductivity have been separated and their temperature dependence has been traced. Anomalies related to the transition of samples to a ferromagnetic state have been found.
