Thermal conductivity measurements at 650°C have been made on aluminum alloys containing up to 58 wt% uranium in the as-cast and heat-treated conditions. The measured conductivity varied from 0.541 cal sec^-1cm^-2°C^-1cm for pure aluminum extruded rod, to 0.081 cal sec^-1cm^-2 °C^-2cm for a heat treated alloy containing 58 wt% uranium. Changes in conductivities, produced by heat treatments, have been related to corresponding changes in the microstructures of the alloys. The thermal conductivities of UAl₃ and UAl₄ were found to be 0.02 cal sec^-1 cm^-2 °C^-1cm by extrapolation.
