Aluminum alloys have evoked a keen interest in recent times for potential applications in marines, aerospace and automotive industries owing to their superior strength to weight ratio, good wear and corrosion resistance. Wear is a cyclic continuous degradation process. Almost 70% failure is due to wear. Experimental investigation have been done to see the effect of normal load on aluminum alloy and to calculate weight loss due to wear. Experiment were done carried using a pin-on-disk test under normal load 0f 10 N TO 25 N, 1800 rpm. It was observed that weight loss increases on increasing load. Also minimum wear occur when specimen is held vertical and maximum wear occur when specimen is held horizontal.
