Designers and consumers now look for materials that are more energy effi- cient, stronger, lighter as well as cheaper. A metal-matrix composite (MMCs) will represents a dominant class of material which can be suitably designed to meet the above requirements. With a variety of reinforcing materials and flexibility in their preliminary processing, Aluminum Metal-Matrix Composites (AMMCs) offer great potential for developing composites with desired prop- erties for larger applications. In this research, a novel composite has been fabricated with Silicon, Magnesium, Copper, Silicon Carbide and Aluminium with 0.5, 0.5, 2.5, 15 and 81.5 percent respectively by weight using the metal- lurgical powder technique. The composite has been studied and investigated its wear behavior in dry sliding mode and found that the wear-rate increases with load applied as well as with sliding-speed and decreases with increase in percent of SiC content in the composites. 1. Introduction Not only are metal-aluminum matrix composites suitable replacements for structural steels, but they are also suitable replacements for aluminum-based alloys in a range of applications in the automo- tive and aerospace industries. They offer a great deal of potential for the production of lightweight materials that do not compromise their strength. To accomplish the same goal of reducing the size while maintaining the same level of strength, it is common practice to substitute the existing mate- rial with one that has a greater yield strength. Another method for reducing overall weight is to replace certain conventional ferrous-based compo- nents with lighter composite materials in particular locations. This can be done selectively. There has been a recent uptick in the use of high-performance and lightweight aluminum metal matrix compos- ites (AMMCs), which are being put to use in an expanding number of consumer-based, aerospace, and automotive applications. This is because it has the capability of establishing a uniform distri- bution of reinforcements inside a matrix element, which results in the production of composite mate- rials of superior quality (Behera et al.)(Behera, Samal, and Panigrahi).
