Metal matrix composites [MMC] are most important materials used for recent works in the industry and engineering applications. Fly ash particles are used in metal matrix composites, are low costand low density are available in large quantities of waste by product in power plants. The adding of fly ash with aluminium reinforcement by using stir casting process it can reduces the cost and density of aluminium material. Metal composite processes are improved mechanical properties like strength, hardness, low density and good wear resistance compared to other metals. In this study,aluminium clad and fly ash chemical analysis is studied before and after mixing and forming as particulate metal matrix composite and comparing the mechanical, physical properties of the MMC at varying % of fly ash addition. By comparison at various levels 15% of fly ash the MMC gives good mechanical and physical properties. This type of MMC is widely useful in light weight vehicles and aerospace application.
