Ferro Rare Earth Mg Si Fe Alloy
Promote graphite spheroidization: spheroidizing agent added to the casting melt, which elements such as magnesium can be combined with the iron in the melt to generate compounds such as MgO, MgS, which in turn promotes graphite spheroidization, increasing the number and size of graphite balls, improving the strength and plasticity of the casting, and reducing the defect rate.
