The granulometry is 1-3 mm. It is supplied in bags for 25 Kg./ pockets for 500 Kg./ pockets per 1,000 Kg.
It is an imported grained granite of high quality, with a minimum purity of 98%, and very low contents of sulfur, volatiles and ashes (only traces). It is used in Gray, Nodular and Steel castings in general, to carbure and correct the Carbon ranges in the base metal. Because it practically does not contain Sulfur, the inclusions of Calcium Sulphate are markedly reduced.
