The major waste material during production of alumina from bauxite by the Bayer’s process is Red mud. It is an insoluble product generated after bauxite digestion with sodium hydroxide at elevated temperature and pressure is known as red mud or ‘bauxite residue’. It constitute of oxides of iron, titanium, aluminium and silica along with some other minor constituents. Based on economics as well as environmental related issues, enormous efforts have been directed worldwide towards red mud. In present work experiments have been conducted under laboratory condition to assess the mechanical properties of the aluminium red mud and silicon carbide composite under different working conditions. This has been possible by fabricating the samples through stir casting technique. To enhance the mechanical properties (tensile, compressive, yield strength and microstructure), the samples were also subjected to heat treatment. Later the obtained results are compared with Al 5005 series materials which are generally used for automobile structures, finally the red mud and Al alloy composite is replaced to Al 5005 series because red mud and Al alloy composite gives good mechanical results.
