Production and mechanical properties of aluminium – Copper alloy reinforced with Al2O3 metal matrix composites

The heavy materials which are used in automobile industry, which are reducing the thermal efficiency, mechanical efficiency and fuel consumption. To overcome this all the factors by finding or introducing new materials such as composites in terms of requirement. The new materials which are used in manufacturing and automobile industry. High specific stiffness and near-zero coefficient of thermal expansion are being experienced in this work. As compared with the parent materials, the addition of new material exhibits better performance in terms of commercial value and the properties of materials. Aluminum has got excellent chemical and physical properties and also it has functioned well in thermal and chemical environments. The may drawback for aluminum is poor thermal resistance and very low toughness. It has been seen that many structural ceramics had poor conductivity when it was mixed with parent alloys. In this work, 10%,20%, and 30% of Al2O3 particles are mixed with Aluminum-Copper alloy to improve the electrical and mechanical properties. The prepared alloy mixtures are fabricated through a stir casting route followed by the sand casting method.
