Fabrication and characterization of Al7075 reinforced by SiC nano particles are investigated in this paper. Al7075 micron sized powder and different amounts of SiC nano sized particles are mechanically milled and then consolidated using hot quasi-static and uniaxial pressing. Microstructural and mechanical behaviour of the samples applying optical microscopy, scanning electron microscopy (SEM), density, micro-hardness, and compressive test are carried out to have a comprehensive investigation. Compressive behaviour of the samples is also examined for both the low and high strain rate loadings. The results show a reduction of relative density as the nano phase content increases. Furthermore, incorporating nano phase could enhance the ultimate strength and micro-hardness of the Al7075 mono phase samples about 15% and 10%, respectively
