Brass materials are categorized in the copper alloys sub-groups with prevailing Zinc element. These materials are utilized from drinking water systems to automotive in a wide range of in-dustrial applications due to superior properties such as strength, formability and corrosion resis-tance. This study aims to characterize and analyze smart and popular conducted manufacturing processes influences on the mechanical and microstructural properties of eco-friendly brass alloy. In this regard, microstructural, hardness, tensile and impact charpy tests have been carried out on extruded, extruded+annealing, forged and forged+annealing eco-brass CuZn40Pb2, CuZn38AS, CuZn21Si3P specimens. The experimental results have demonstrated that the manufacturing process type extremely influences the materials mechanical and microstructural properties.
