CFC Egypt manufactures a complete range of non-ferrous treatment products from our Sadat City plant. Our aluminium flux and degassing range addresses every stage of the aluminium melting cycle \u2014 from protecting the melt surface against oxidation through covering and drossing fluxes, to removing dissolved hydrogen via degassing flux powders and tablets, to recovering metal from hot skimming and cleaning furnace walls. For copper and copper-alloy foundries, we supply purpose-formulated copper fluxes and degassing tablets that prevent the oxidation and gas pickup that degrade bronze and brass castings.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Aluminium is now the dominant casting metal for automotive structural components \u2014 cylinder heads, engine blocks, gearbox housings, suspension knuckles, and wheel hubs are all routinely cast in aluminium alloys by high-pressure die casting (HPDC), low-pressure die casting (LPDC), and gravity permanent-mould processes. Degassing, covering, and release chemistry are critical to achieving the internal soundness, dimensional accuracy, and surface quality demanded by automotive OEMs.\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Bronze and brass castings \u2014 propellers, pump impellers, valve bodies, bearings, and decorative fittings \u2014 require clean melts free of hydrogen gas and surface oxide inclusions. Copper alloys absorb gas rapidly and are sensitive to oxidation; covering and degassing flux chemistry applied at the furnace is the primary means of controlling melt quality before the pour. CFC copper fluxes are formulated for the full range of copper alloy grades including Cu-Sn bronze, Cu-Zn brass, and Cu-Al aluminium bronze.\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 castings are used extensively in electrical infrastructure \u2014 transformer housings, bus bars, cable connectors, motor housings, and switchgear components.

Non-ferrous metal treatment is the foundry chemistry used to melt, refine, and cast non-iron metals \u2014 primarily aluminium, copper, and their alloys \u2014 covering fluxes, degassing, grain refinement, and modification that control melt cleanliness, gas content, and final mechanical properties. It includes all the chemical products applied to the melt or the mould surface to remove impurities, prevent oxidation, control solidification structure, and ensure clean, sound castings. The two main branches are aluminium treatment and copper treatment, each requiring different chemistry matched to the respective metal's thermochemistry and casting process.\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 mould coatings and specific binder systems. Non-ferrous treatment covers aluminium, copper, and their alloys, melted at lower temperatures (650\u20131100 \u00b0C), and uses a fundamentally different chemistry: degassing fluxes to remove dissolved hydrogen, covering and drossing fluxes to protect the melt surface from oxidation and recover metal from dross, demagging and alkali-removal flux for secondary aluminium, and lighter-duty release agents for permanent dies and sand moulds. The two ranges serve distinct engineering and chemical requirements and are not interchangeable.\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

Aluminium dissolves hydrogen readily from atmospheric moisture and from wet moulding materials during melting. As the melt solidifies, the solubility of hydrogen drops sharply and dissolved hydrogen comes out of solution as gas porosity \u2014 microscopic bubbles trapped within the solidified casting. Gas porosity reduces tensile strength, fatigue life, pressure tightness, and machinability, and is a primary cause of casting rejection. Degassing treatments \u2014 using flux powders that release reactive gas into the melt, or compact degassing tablets that are plunged below the surface \u2014 nucleate hydrogen-rich bubbles which rise and escape before the pour. Effective degassing is non-negotiable for structural and pressure-tight aluminium castings.\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

Covering fluxes are powder or granule mixtures spread on the surface of molten aluminium or copper to form a protective blanket that prevents contact between the liquid metal and the surrounding atmosphere. Without a covering flux, the melt surface oxidises continuously, forming a growing oxide skin and dross layer that can become entrained in the casting and cause inclusions or surface defects. Covering fluxes reduce oxidation losses, suppress dross formation rate, and \u2014 when formulated with a drossing action \u2014 help recover entrapped metal from the dross layer, improving metal yield and reducing scrap. They are applied continuously during holding and between taps.\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
