Matrix Composites (MMCs) have appeared as a significant materials for structural,
wear, thermal, transportation and electrical applications. Aluminium has high
strength-to-weight ratio and strength-to-cost ratio equivalent to other
monolithic commercial alloy. It has found that Aluminium has a wide range of application
in areas where lightweight is in main consideration. But its low wear
resistance gives it a low tribological ranking 
which does not allow this in applications such as automotive works where
high wear resistance is desired K.L tee To improve its wear
resistance, Al-base composites reinforced with ceramic particles have been

            To improve the wear performance
generally ceramic particles like SiC, TiC, TiB2, ZrB2,AlN,
Si3N4, Al2O3, and SiO2 used
as reinforcement material in Aluminium matrix.S suresh et al.. Ceramic
particle selected as a reinforcement in accordance to their high young’s
modulus, low specific gravity, superior Vickers hardness, good thermal
conductivity, high electrical conductivity, high elastic modulus and hardness,
high melting point, superior wear resistance and good thermal stability. Among
this wear resistance is one the valuable factor which has a very important role
in engineering applications.

A20X belongs to Al-Cu family which has been developed and patented by Aeromet
International Ltd which has a wide range of aerospace applications. A20X is
a very high strength aluminium alloy which includes the MMPDS (Metallic
Materials Properties Development and Standardization) approved A205
casting alloy and AM205 powder for additive manufacturing. A20X basically an
aluminium copper alloy with highly refined microstructure and a unique
solidification mechanism which provide it very high strength, fatigue and
thermal characteristics compared to other alloys. Aluminium A20X can be prepared
by casting route and powder route.

In this paper study of
A20X alloy in various condition has been carried out by performing their wear behaviour
as well as SEM image with Energy dispersive X-Ray spectroscopy for analysis the
composition of the wear debris
