FeSi Sr1 / FeSi Sr2

Especially used in Grey Cast Iron

FeSi Sr 1 is a ferrosilicon alloy with ultra-low contents of calcium and aluminum and a high percentage of Strontium. Its principal application is in the production of grey cast iron, when searching for reduction in chilling, without altering the structure.

FeSi Sr 2 – Indicated when Strontium addition is needed. However, a limitation of Silicon content has to be observed in the cast.
