MG 4R is a low magnesium alloy that contains relatively high levels of Rare Earth elements. Due to the relatively low Magnesium level, the alloy is not as reactive as 6% MgFeSi alloys.
The higher levels of Rare Earths provide nodulizing effects so that ductile irons can be produced with somewhat lower Magnesium residuals compared to 6% Mg, 1% TRE alloys. MG 4R is useful in the Flo-Tret process.
