Aluminium metal matrix composites are widely used in various manufacturing sectors like automotive, aerospace,
electrical etc. Aluminium metal matrix composites provide better physical and mechanical properties e.g. tensile
strength, toughness, strength to weight ratio etc. as compared to its base alloy. Now a days, consumption of
aluminium casting has increased from 85,000 ton in 1995 to 180,000 ton in year 2010. Among all the fabrication
processes, stir casting technique is best suited for aluminum metal matrix composites because of its simplicity and less expensive. Normally, reinforcements added in aluminium metal matrix composites are SiC, B4C, Al2O3, TiC etc.
