Both copper wires and ferrous chassis are included in automotive scrap. Copper can directly influence the mechanical properties of steel products, and is generally considered to be a harmful tramp element. In contrast, copper is actively used for various sintered machine parts, because the Fe–Cu–C type can combine performance and economical efficiency, and does not require the advanced technique. Thus, a study was conducted utilizing powder metallurgy and Fe–Cu alloy powder to determine the possibility of using the rational processing of recycling copper-rich scrap. The microstructure and strength of the Fe–2%Cu–0.8%C compacts sintered with Fe–Cu alloy powder, were considerably influenced by the Fe/Fe–Cu powder mass ratio. The weight change decreased with the increase in the Fe/Fe–Cu powder mass ratio. This shows that graphite was consumed to reduce the reaction of oxide film on the Fe–Cu alloy powder surface. The strength of sintered compacts increased as the Fe/Fe–Cu powder mass ratio increased. For example, when Fe–Cu alloy powder is used in conjunction with an oxide film, the desirable Fe/Fe–Cu powder mass ratio is more than 3 in order to obtain a sintered compact with transverse rupture strength higher than 700 MPa.
