Astheresultoftheinvestigation, akindofRe-Cu-zn-Mg-Si-Fevermicularizingalloywithcompositionofw (RE) 15% ~ 22%, w (Cu) 15% ~ 22%,air jordans, w (Zn) 2.5% a 4%, W (Mg) 0 ~ 3%, w (Si) 29% -32% wasobtained. Thiskindofvermicularizingalloyhastheadvantagethatitsproperadditionrangeiswide, SOitieneficialtoobtainstablevermicularity. Keywords: vermiculariron; vermicularizingalloy; vermicularizingrangewideningelement the compacted graphite cast iron has excellent performance, so 60 years from the last century, engineering has been paying attention at home and abroad, and its increasingly wide range of applications. Of rare earth rich in resources, the world's first production of rare earth ferrosilicon alloy compacted graphite iron country.
