Foundry raw materials are the base inputs and additives that go into the melt \u2014 ferro alloys, carbon raisers, inoculants, and metallurgical inputs \u2014 supplied to control composition and metallurgical quality.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Controlling the chemical composition of the melt is the foundation of casting quality. The right ferro alloy additions set the carbon equivalent, silicon level, manganese, chromium, and trace element content that determine the mechanical properties of the solidified casting. Carbon raisers restore carbon lost to oxidation or adjust the charge composition to target. Inoculants added to iron melts control the graphite structure that governs tensile strength and machinability in grey and ductile iron. CFC Egypt supplies EGYFLUX SSF from our Metallurgical Chemicals division, while broader raw material sourcing \u2014 ferro alloys, carbon raisers, and other metallurgical inputs \u2014 is available through our Trading Division, which sources and supplies metallurgical inputs to complement the manufactured product range.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Grey iron foundries use ferro silicon and carbon raisers in every heat to maintain carbon equivalent and control graphite type. Inoculants are added at the ladle or in-stream to ensure consistent flake graphite distribution, mechanical properties, and machinability across the batch. Raw material consistency \u2014 particularly in sulphur and nitrogen content of carbon raisers, and in the active element composition of inoculants \u2014 directly determines casting consistency and scrap rate.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Ductile Iron Foundries\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t

Ductile iron production requires very low sulphur base iron (typically below 0.01% S) before magnesium treatment \u2014 making desulphurising ferro alloys and low-sulphur carbon raisers critical inputs. After Mg treatment, inoculation is mandatory to nucleate the spheroidal graphite that gives ductile iron its high elongation and impact strength. The iron chemistry window for ductile iron is narrow; consistent raw material quality reduces the risk of undercooled graphite structures and carbide formation that would cause casting rejection.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Steel Casting\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t

Steel foundries use ferro alloy additions \u2014 ferro manganese, ferro silicon, ferro chrome, ferro nickel, ferro molybdenum \u2014 to achieve the specified composition of carbon, alloy, or stainless steel grades. Carbon raisers are used to adjust carbon levels in the melt and are selected for minimal sulphur and nitrogen contribution. The alloy addition sequence and timing in the EAF or induction furnace must be optimised to minimise loss of volatile alloying elements and achieve the target analysis within the narrowest possible compositional range.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Aluminium and copper foundries use master alloys \u2014 aluminium-silicon, aluminium-copper, aluminium-titanium-boron \u2014 to adjust composition in the furnace. Grain refiners and modifier alloys are specialist raw material inputs that control the solidification microstructure of aluminium castings \u2014 finer grain and modified silicon eutectic both improve mechanical properties and reduce sensitivity to porosity.
