AB  - In the present research, Aluminum, Magnesium, Silicon with additives of Alumina particles matrix powders were compacted using powder metallurgy method. The green compacts of both alloy (Al-Mg-Si-Cu) and composites (Al-Mg-Si-Cu/Al<sub>2</sub>O<sub>3</sub>) mixed powders were compacting using hydraulic press uniaxial at 400 MPa. The compacted mixtures Al-alloy and Al-composite were carried out by the sintering treatments at 460&deg;C for 1.5 h. Over all the evolutions of the precipitates and hard second phases of the Al-matrixes P/M after the sintering process were examined using the X-Ray Diffraction-(XRD) and Scanning Electron Microscopy-(SEM). Outcomes of microstructural the compacted Al-PM alloy and composite investigated having a precipitations and second Al<sub>2</sub>O<sub>3 </sub>hard within the matrix during steps of sintering treatment. The highest Vickers hardness recorded of Al-Mg-Si-Cu/Al<sub>2</sub>O<sub>3</sub>p composite under sintering at 460EC.
