What is rare earth silicon magnesium alloy, what are the uses

Rare earth silicon magnesium alloy is used as a spheroidizing agent for casting. Its role is to make the graphite in the casting iron spheroidization, thus enhancing the performance of the casting. Main components: magnesium, a small amount of rare earths, silicon and a small amount of calcium and barium. Magnesium plays a major role in spheroidization. Rare earth silicon magnesium alloy magnesium is divided into effective magnesium and ineffective magnesium, only the free state (metal state) of magnesium for the effective magnesium, magnesium burned in the production process of magnesium oxides produced in the spheroidization process for the ineffective magnesium.
