72 silicon iron powder 0-3mm multi particle size

Ferrosilicon 72% is a common and popular model in Ferroalloy with a silver grey surface, it is mostly used as the inoculant and nodulizer in the casting industry and steel making. Ferro silicon 72 Lump, as an additive in the production process of ferrous metals, will change several properties of the ferroalloy. The corrosion resistance of the new compound was improved by adding ferrosilicon 72% of into the alloy.  In the meantime, the high temperature and heat resistance of new alloys is increased.     Item% Si P S C Al ≤ FeSi75 75 0.03 0.02 0.15 1 FeSi75 75 0.03 0.02 0.15 0.5 FeSi75 75 0.03 0.02 0.1 0.1 FeSi75 75 0.03 0.02 0.05 0.05 FeSi75 75 0.03 0.02 0.02 0.02 FeSi72 72 0.03 0.02 0.15 1 FeSi75 75 0.03 0.02 0.15 0.5 Packaging of Ferrosilicon Products: Specification granularity: natural block, 10-100mm, 10-60mm, 3-10mm, 1-3mm, 0-1mm or customized…
