The aluminium Metal matrix composites (MMCs) have extensively used in industrial applications due to the lighter weight with high specific strength, good thermal behaviour and high stiffness. But the Processing of aluminium at high temperature is very difficult and complex task due to its reactive nature. In the present work AMCs with graphite, SiC, Mg and zinc along with fly-ash as reinforcements fabricated using PM approach. Sintering carried out using powder silicon dioxide in place of inert gas or vacuum chamber with designed arrangements. Characterisation of composites carried out using hardness testing, wear rate and measurement of friction coefficient. Present way of sintering give more effective results than conventional methods along with considerable reduction in manufacturing cost. Effect of varying sintering time, sintering temperature and compaction pressure observed using taguchi approach on output properties of produced. Composite with 800 kN at 660oC for 3 of sintering has better hardness compared with all composites. But with 800 kN at 690oC for 4.5 hours of sintering have better wear behaviour compared with all composites.
