Abstract: Aluminum alloys are promising for structural applications due to their high strength to weight ratio, resistance to corrosion and light weight,Light Weight. Aluminum is a very light metal with a specific weight of 2.7 g/cm3, about a third of that of steel . Aluminum alloy Matrix composites reinforced with particles like ceramic possess higher strenght and hardness , using aluminum 7075 as parent metal powder particles as reinforcement , most important benefit of 7075 aluminum is its high strength .FSP technique has been used for fabrication of surface composites. While it doesn't have the same level of corrosion resistance or weldability that other common alloys due, it's resistance to stress and strain makes it highly useful in aerospace applications where it allows for weight savings over steel, multi walled carbon nanotubes produced by the catalytic carbon vapour deposition (CVD) process, MWCNT improves the mechanical performance thermal conductivity, electrical conductivity, and permeation barrier properties of a range of composites and formulations. Processing parameters are have been set . FSP for AL 7075 is successfully done with reinforcement 3 percentage of MWCNT . The result workpiece is cut into tensile specimen according to ASTM standard using wire cut EDM.This result suggests that the friction stir processing is a useful method as microstructure refinement for the 7075-aluminum alloys. In this paper, the mechanical properties of the friction stir-processed materials at room and high temperatures are briefly discussed. The mechanical properties of the unprocessed materials are also compared with those of the processed materials
