Ferrosilicon 75 from the HONGSHUN ferroalloy factory, is produced by smelting silicon and iron at high temperatures. This alloy contains 75% silicon by weight, with the remainder being iron and trace impurities. Its exceptional chemical and physical properties make Ferrosilicon 75 widely used in the steelmaking and foundry industries.
As a professional ferro silicon supplier, we mainly supply 75 ferrosilicon lumps, FeSi75 granules and FeSi75 powders.
