The reliability of the mechanical properties of any product plays an important role in the longevity of the product to work properly under various working conditions. In the present study, the effect of preparing brass alloy on its mechanical properties was experimentally studied. Samples of brass (60% Cu-40% Zn) were prepared by hot iso-stating pressing (HIP) sintering method and some main mechanical tests were performed on them included porosity, density, hardness and compression tests. Results of these tests were compared with corresponding tests on commercial brass alloys produced by casting in order to show the effect of the method of preparing on their mechanical properties. There was a significant improvement in the hardness and strength of the sintered alloy due to the increasing in density and decreasing in porosity comparing with the corresponding other casting's alloys. Results showed an improvement in the density values by 8.4% as a result of the significant reduction in the porosity values from 8.65% to about 0.43%. As a result, the strength of the alloys prepared by the heat pressing method has jumped to a value of 600MPa compared to the traditional castings that have a strength of 343MPa.
