Division 03 — Trading Division — Pure Metals

Saf Metaller

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.

Frequently Asked Questions

Technical questions on silicon metal and magnesium metal applications answered plainly. Contact our team for specific process recommendations.

Silicon metal is a high-purity form of elemental silicon — typically 98.5–99.7% Si — produced by reducing silica with carbon in an electric arc furnace. In metallurgy, silicon metal is used principally as the silicon source for producing aluminium-silicon alloys (where it is alloyed directly with aluminium to create casting and wrought alloy compositions), for manufacturing ferrosilicon, and as a raw material for silicone polymer production. Silicon metal grades are classified by their iron, aluminium, and calcium impurity levels (e.g., 553, 441, 3303 grades), with higher-purity grades used for chemical and electronic applications.

Silicon metal is essentially pure elemental silicon (98–99.7% Si) with iron as the principal impurity. It is used where a clean silicon source is required — aluminium alloying, silicone manufacture, and semiconductor applications. Ferro silicon (FeSi) is an alloy of iron and silicon (typically 65–75% Si) specifically designed for addition to iron and steel melts where both a silicon increase and a compatible iron carrier are needed. For iron and steel deoxidation and alloying, ferro silicon is preferred because it dissolves faster and the iron carrier does not affect the melt chemistry. For aluminium alloying, silicon metal is the standard silicon source.

Magnesium metal ingot (99.9% Mg) is used in foundry applications primarily as the raw material for producing ferro silicon magnesium (FeSiMg) nodulisers used in ductile iron production, and as a direct addition agent for ductile iron treatment via the wire injection or sandwich process. It is also used as a sacrificial anode material for cathodic protection, as a desulfurisation agent in hot metal treatment, and in the production of magnesium alloys for die casting and other applications. The high chemical reactivity of pure magnesium requires careful handling — storage in cool, dry conditions away from moisture and oxidising materials.

Magnesium is the element responsible for transforming the graphite morphology in cast iron from flake (grey iron) to spheroidal (ductile iron) during solidification. When magnesium is added to a grey iron melt at levels of approximately 0.03–0.05% residual, it reacts with dissolved sulfur and oxygen to eliminate the sites on which graphite flakes preferentially nucleate, instead promoting growth of spheroidal (nodular) graphite. Ductile iron has dramatically higher tensile strength, elongation, and impact resistance than grey iron because spheroidal graphite does not act as a stress concentrator the way flake graphite does. The magnesium is usually delivered as FeSiMg noduliser rather than pure magnesium metal.

CFC Egypt's Trading Division sources silicon metal and magnesium metal ingot from established producers and supplies them to foundries, aluminium processors, and industrial users in Egypt and the MENA region. These are traded materials — CFC Egypt does not manufacture pure metals — and supply is supported by specification documentation and technical advice on appropriate grade selection for the application.
