Currently, new and uncommon materials are being more used in automotive components, such as the manufactured by Powder Metallurgy due to new cost reduction strategies adopted by carmakers. The companies are searching more and with stronger aggressiveness the ways of finding cost reduction opportunities of a product and/or process. With this intention and for being it tracked by technical and commercial interests, new departments are being created with different names and structures. The ways to find out a reduction of viable cost are discussed in different ways of approaching of this question, which may be originated from the standardization of an item utilized in similar products, in the removal of components with questionable importance, in the change of manufacture processes, in the localization of items and finally, in the change of material and/or project. Starting from known approaches, the present work relates the most different ways of proposals and characterizes and quantifies them in graphical forms, adopted procedures, and by descriptions of ways pursued to reach a financial goal of reduction, mentioning typical examples of proposals with potential of implementation after a technical and critical analysis. Finally, the focus of this study is the approach of materials and specifications, said currently as the most complex and difficult field; however, with inexhaustible ways in the last instance in the field of Cost Reductions, and then the acquired knowledge should be used in sintered material.
