Controlled melt chemistry starts with the right input.
OPTES Group supplies foundries and melt shops across MENA and Africa with selected ferro alloys, aluminum-based master alloys, and pure metals through a trusted global sourcing network.
From melt chemistry adjustment and deoxidation to grain refinement, eutectic modification, and high-purity elemental additions, OPTES connects each operation to the correct metallurgical input.

Product selection depends on the base metal system, target chemistry, required metallurgical function, addition practice, and final casting or alloy performance. Ferro alloys support composition adjustment and deoxidation in iron and steel melts; aluminum-based master alloys support grain refinement, eutectic modification, and controlled alloying in aluminum melts; and pure metals are selected where high elemental purity is required for critical additions. For ductile iron nodularization and inoculation, OPTES provides specialized Elkem Norway solutions through a dedicated product page.
OPTES supplies three main product families: general ferro alloys, aluminum-based master alloys, and pure metals. These products are sourced through a global partner and supplier network to support foundries and melt shops across MENA and Africa. Specialized FeSiMg nodularizers and inoculants are handled through a separate Elkem Norway product page because they belong to a dedicated ductile iron treatment range.
Ferro alloys are added to iron and steel melts to adjust chemical composition, support deoxidation, and introduce alloying elements such as silicon, chromium, manganese, phosphorus, or molybdenum. Their performance depends on chemistry, size, recovery rate, dissolution behavior, melt temperature, and addition practice. OPTES supports customers in selecting the suitable ferro alloy according to melt process and target specification.
Aluminum-based master alloys are concentrated alloying additions used to introduce controlled amounts of titanium, boron, strontium, silicon, copper, manganese, iron, chromium, nickel, vanadium, or zirconium into aluminum melts. They are used for grain refinement, eutectic modification, strength enhancement, deoxidation, and specialty property control. Correct selection depends on alloy system, target chemistry, addition form, melt temperature, and expected recovery.
Al-Ti master alloys introduce titanium for grain refinement in aluminum melts, while Al-Ti-B master alloys combine titanium and boron to form more effective nucleation sites for aluminum grain structure control. Selection depends on the alloy type, melt cleanliness, required grain size, holding time, and casting process. OPTES can support customers in identifying the suitable grade according to process requirements.
Pure metals are selected when the process requires a high-purity elemental addition or when the alloying route must avoid unwanted accompanying elements. They are commonly used for chemistry correction, high-purity alloy production, and specialized metallurgical applications. Selection depends on purity requirement, dissolution behavior, contamination limits, and the final alloy specification.
The correct alloying input should be selected according to base metal, target chemistry, addition efficiency, recovery rate, impurity limits, melting temperature, and final casting or alloy performance. Product selection should not be based only on product name; it must consider actual melt conditions and process requirements. OPTES can support customers by reviewing the application and recommending the suitable product family, grade, and sourcing option.
Let our metallurgy experts help you select the optimal alloying input for your melt process.
