This project aims at improving the physical and mechanical properties of 6061 aluminum by powder metallurgy and hot pressing to use in aviation industry specially in air-style building and flying objects, especially in the construction of helicopter rotor shell hydraulic systems, helicopters and airplanes. The effect of different parameters such as temperature, time and pressure required to stabilize the powder onto the target parameter namely density and compressive strength of the aluminum sample is placed. The powder of aluminum 6061 through spray liquid which was prepared by mechanical alloying and a 40- hour basis nanostructures has become a mill wear. In designing experiments, Taguchi has been used. Based on that there are 9 series of experiments involving three variables, and each of these three involving three levels. Physical and mechanical properties of these tests include density and tensile strength So that increased pressure directly increases the density and strength, but increasing the temperature and density are directly and inversely related to the strength. However when the temperature increases and the density increases and the other decreases the tensile strength of the sample decreases. In sum in order to investigate the structure and grain size of the powders and the sample - for test, scanning electron microscope and X-ray diffraction experiment was performed
