In this paper, some mechanical properties of the forged metal are investigated. the chemical analysis , the microscopic examination and the hardness testing were carried out. The samples were taken from the three types of metals( iron, copper, aluminum). The Impact forging ( open die forging ) process was carried out on the three types of the metals. The hardness testing were carried out before and after process. It is noted that the metals are affected by the impact forging process. It was found that the metals specimens which were subjected to the forging process may decrease in toughness, while the hardness increased in proportional increasing with the energy of the impact forging process. The microstructure examination shows that the samples remained intact after the forging process and whiteout happening the wear or cracks.
