About This Company

Ferroglobe PLC produces advanced metallurgical products spanning ferroalloys, specialty metals and electrodes, supported by several mines that provide essential raw materials. Its range includes silicon metal, manganese alloys, ferrosilicon, calcium-silicon, silica fume, pulverized products and silicon materials for advanced technologies. The company serves customers globally and supplies alloy-industry inputs alongside materials for steelmaking and foundry operations.

For iron foundries, the company manufactures ferrosilicon-based inoculants and FeSiMg nodularizers used in liquid cast iron to control matrix structure, promote spheroidal graphite and improve casting properties. Its steel-processing portfolio includes lime-based ladle desulfurizers, slag conditioners, synthetic slags, calcium aluminates and fluorspar. Products can be packaged in bulk pneumatic or dump formats, super sacks, or 50-pound palletized bags; calcium-silicon is also supplied as filled cable or grains for powder injection.
