Successes of all industries like automotive, aerospace, marine and electronics applications mainly depend on reducing weight and at the same time increase in life, millage and appearance of their products. It mainly depends on developing new and cost-effective materials that have high weight to strength ratio, bio degradable and at the same affordable. The, composite materials have a steady growth, penetrating and conquering new market condition. Generally composite materials emerge a significant part of the engineered materials market, ranging from day today products to complex applications. Aluminium alloy (LM6) is used as a metal matrix and coconut shell ash (CSA) as reinforcement for developing a new metal matrix composite material. A coconut shell ash 6% by weight is added and an aging process is done at temperature 175°C to develop a metal matrix composite fabricated by stir casting. The wear properties of the composite is studied for all test specimens. Wear properties of the metal matrix composite were studied by performing a dry sliding wear test using pin-on-disc wear tester. The result of the wear test shows that wear rate of composites is higher than the pure alloy.
