Powder Metallurgy P.M. is a technique that uses the principle of forming metal alloys from the mixture of metal powders to form materials with particular characteristics such as controlled hardness, mechanical strength, and porosity. It is possible to develop this control by varying the parameters, such as temperature and pressure of compaction, reaching the desired levels. This paper evaluated the behavior of surface porosity in the variation of the copper-nickel concentration of dissociated powders, maintaining sintering temperature and compaction pressure constant. To determine the porosity of the copper-nickel alloy, the Scanning Electron Microscope (SEM), ImageJ, and statistical calculations used to generate graphs to represent the results. The results indicated that there was no linear behavior of the surface porosity.
