Property Enhancement of Aluminium Alloy 2000 Series Strengthened by Synthetic, Self-Lubricant and Natural Reinforcements

Wider usage of aluminium alloy composites can be seen in several sectors like automobile, aerospace and marine application. Current article clearly explains the property enhancement of aluminium alloy composites reinforced with natural materials and is compared with synthetic as well as hybrid reinforcements. AA2219 is taken as a base metal and BC, WC, Al2O3, MOS2, Graphite, Sea shell powder (SSP) are taken as reinforcing agents. Stir casting technique is adopted to fabricate a test specimen since it is flexible and easy to cast among remaining casting methods in metal matrix composite. Above mentioned reinforcements are taken with a weight percentage of 1, 2 and 3. For property enhancement evaluation, hardness test is carried out. It is observed from the evaluation, natural reinforcement result in better enhancement than the synthetic reinforcements.
