Division 03 — Trading Division — Pure Metals
Pure Metals
Pure metals are elemental metal materials — silicon metal and magnesium metal ingot — supplied at high purity for use as alloying inputs, nodularisation agents, and direct additions in foundry and metallurgical processes. Unlike ferro alloys, which are iron-based carrier alloys, pure metals introduce the target element with minimal dilution, making them the preferred choice where the iron content of a ferro alloy addition is undesirable.
CFC Egypt's Trading Division sources silicon metal and magnesium metal ingot (99.9% Mg) for supply to aluminium foundries, aluminium casthouses, iron foundries, and industrial processors across Egypt and the MENA region. Silicon metal is the primary silicon source for Al-Si alloy production; magnesium metal ingot serves as the raw material for FeSiMg noduliser manufacture and as a direct addition agent in ductile iron treatment. Both metals are traded materials — supplied with specification documentation and supported by technical application guidance.
01
What We Supply
Two pure metal inputs covering the silicon and magnesium requirements of aluminium processing and iron foundry operations.
01
Silicon Metal
High-purity silicon metal (98.5–99.7% Si) produced by carbothermic reduction of silica. The primary silicon source for producing aluminium-silicon alloys — including hypoeutectic casting alloys (A356, LM25) and wrought Al-Si alloys. Also used in ferrosilicon manufacture, silicone polymer production, and as a silicon addition for iron melts where iron contamination from FeSi is not acceptable.
02
Magnesium Metal Ingot (99.9% Pure)
High-purity magnesium ingot (minimum 99.9% Mg) for use as the magnesium source in FeSiMg noduliser manufacture, as a direct addition agent in ductile iron treatment via sandwich or wire injection processes, in magnesium alloy production for die casting, and as a desulfurisation reagent in hot metal treatment. Supplied in standard ingot form with purity and impurity certificates.
02
Where Pure Metals Are Used
Silicon metal and magnesium metal serve as fundamental raw material inputs across aluminium processing, iron casting, and chemical manufacturing.
Aluminium Alloy Production
Silicon metal is charged directly into aluminium melting furnaces to raise the silicon content of the melt to the target alloy composition. Al-Si casting alloys contain 5–13% Si; silicon metal (rather than FeSi) is used because the iron present in FeSi would reduce electrical conductivity and increase the formation of hard, brittle iron-bearing intermetallics in aluminium alloys.
Ductile Iron Production
Magnesium metal ingot is the primary raw material used by FeSiMg noduliser manufacturers. It is also used directly in ductile iron production via the wire injection process, where a magnesium-containing wire is fed into the ladle under a steel cap to control magnesium vapour and achieve a consistent residual magnesium level for reliable nodularity.
Magnesium Alloy Die Casting
Pure magnesium ingot is the base metal for magnesium alloy die casting — used in automotive and electronics applications where the high strength-to-weight ratio of magnesium alloys (such as AZ91 and AM60) provides significant weight savings. Magnesium die casting requires specialist equipment and handling procedures due to the fire risk associated with molten magnesium.
Chemical & Industrial Applications
Silicon metal is the feedstock for silicone polymer and resin manufacture, and is used in the production of silicon carbide, polysilicon for photovoltaics, and specialty chemicals. Magnesium metal is used for sacrificial anodes in cathodic protection systems, in chemical synthesis, and as a desulfurisation agent for hot metal (blast furnace iron) before steelmaking.
