In this work, aluminium is combined with carbon nanomaterials to enhance the mechanical properties of aluminium–carbon alloys, using powder-metallurgy technology. The powders are mixed in specific weight ratios and varying reinforcement concentrations, with aluminium serving as the base material and carbon nanomaterials as the reinforcement. These powders are pressed into moulds with a diameter of 10 mm, producing six samples of aluminium–carbon-alloy compacts. The mechanical properties of the prepared samples, such as hardness, porosity, and density, are studied. The best hardness value achieved is of 32.5 g/mm2. As observed, porosity increases with the reinforcement content after the second sample, while reinforcement content inversely affects both bulk and apparent densities, decreasing them as the reinforcement content is increased.

KEY WORDS: aluminium, nanocarbon, density, porosity, hardness, powder metallurgy, sintering
