The addition of lead to the copper alloys increase the machinability of thework material (without reference here to environmental factors) and reduces the overall production cost of the components at different stages, despite copper being expensive, which makes a challenging task to replace lead. Since lead is dangerous to human health. Many materials are considered to replace lead in brass and silicon is one of the alternative. This thesis characterizes the lead and the lead free brass's surfacemetallurgy for a certain cutting data. The study includes identification of alteredmaterial zones (AMZ) defined by the plastic deformation, hardness alterationsand grain distributions.The study results include the analysis of deformed subsurface region andcomparison exemplifying differences between the two materials under twodifferent studies. / Lead free brass
