An experimental setup to measure the thermal contact resistance across aluminium assemblage is described and from
that, the results obtained are presented. A distinctive experimental set-up was fabricated to carry out axial heat flow steady state
experiments for the estimation of thermal contact resistance at the assemblage of two materials. Two different materials
(Aluminium and Copper) are selected for the experiments considering their mechanical and thermal properties. A precise
estimation of thermal contact resistance for the interface of sets of similar materials was one of the most important results of this
research. The effects of the material properties, surface roughness and the load conditions (nominal interface pressure) have
been studied and acknowledged. in addition, the experimental results are compared with theoretical models, showing their
limitations to make a precise estimation of the thermal contact resistance in the range of the used parameters. The resulting
thermal contact resistance .
