Ferrous metal treatment is the foundry chemistry used to cast and finish iron-based metals \u2014 grey iron, ductile iron, and steel. It covers the mould and core coatings, moulding materials, feeding and surface treatments, patching compounds, and parting agents applied during casting to control metal quality, surface finish, and dimensional accuracy.<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

CFC Egypt manufactures a complete range of ferrous treatment products from our Sadat City plant. Every product is engineered for the thermal and chemical demands of iron and steel casting: refractory coatings rated to withstand pouring temperatures, binder systems that build moulds capable of holding dimensional tolerances, and feeding compounds that eliminate shrinkage defects by keeping risers liquid through solidification. Whether you run a green-sand grey-iron foundry or a steel investment-casting operation, we supply the chemistry for the full casting cycle.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Ferrous metal treatment is the foundry chemistry used to cast and finish iron-based metals \u2014 grey iron, ductile iron, and steel. It covers the mould and core coatings, moulding materials, feeding and surface treatments, patching compounds, and parting agents applied during casting to control metal quality, surface finish, and dimensional accuracy. Without these chemicals, ferrous castings suffer from burn-on defects, veining, shrinkage porosity, and dimensional scatter that make them unsuitable for engineering applications.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

The main chemical groups in ferrous metal treatment are: refractory mould and core coatings (zircon-, magnesia-, or graphite-based suspensions applied to mould surfaces before the pour); sand binders and moulding additives that build dimensionally stable moulds; exothermic and insulating feeding compounds that keep risers liquid during solidification to prevent shrinkage defects; refractory patching materials for ladles and furnaces; and release and parting agents that allow clean separation of the solidified casting from the mould or pattern. CFC Egypt manufactures products across all five of these groups under the EGYCOAT, EGYBINDER, EGYSET, EGYFEED, EGYPATCH, and EGYPART product families.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Ferrous metal treatment targets iron-based alloys \u2014 grey iron, ductile iron, and steel \u2014 which are cast at 1350\u20131600 \u00b0C and require high-temperature refractory coatings (zircon, magnesia) and specific binder systems suited to that thermal range. Non-ferrous metal treatment covers aluminium, copper, and their alloys, which melt at lower temperatures (650\u20131100 \u00b0C) and use different chemistry: degassing fluxes to remove dissolved hydrogen, covering and drossing fluxes to protect the melt from oxidation, and lighter-duty release agents for permanent dies and sand moulds. CFC Egypt supplies both ranges \u2014 our non-ferrous products are listed under the Non-Ferrous Metal Treatment category.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Coating selection depends on three main factors: the metal being cast (grey iron, ductile iron, or steel), the moulding system (green sand, resin-bonded sand, or shell), and the casting complexity and finish requirement. Zircon-based coatings are the standard choice for steel and high-quality ductile iron because zircon is chemically stable at 1600 \u00b0C and produces a very smooth casting surface. Graphite or carbon coatings suit grey iron in green sand because they reduce burn-on and are cost-effective at scale. Magnesia-based coatings are specified for high-manganese steels where silica-based refractories would react with the metal. Application method (dipping, brushing, or flow-coating) and dilution ratio must also be matched to the specific coating product and mould geometry. Our technical team supports product selection for your process conditions.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Ferrous foundry chemicals are used wherever grey iron, ductile iron, or steel castings are produced at scale. The largest consuming industries are automotive (engine blocks, cylinder heads, brake discs, differential housings), agricultural and construction machinery (gearboxes, hydraulic components, counterweights), water and gas distribution (ductile iron pipes, valves, and fittings produced by centrifugal or sand casting), and general engineering (pump casings, machine frames, and tooling). Any foundry that pours ferrous metals will require at minimum a mould coating, a binder system, and a release agent.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t
