Cored Wires: Manufacturing, Applications, and Market Scope in India

Cored wires are essential consumables in modern steelmaking and foundry operations, used to introduce precise alloying elements and deoxidizers into molten metal. These wires consist of a metallic sheath—typically low-carbon steel—filled with a powdered core of alloying materials. The filling composition varies based on the metallurgical need, allowing for controlled and efficient addition of elements such as calcium, carbon, sulphur, aluminum, or rare earths. The sheathing process involves continuous cold rolling or strip wrapping followed by compaction to ensure uniform distribution and density.

In India, the demand for cored wires is driven by the steel, ductile iron, and foundry sectors. Commonly used types include:

• CaSi (Calcium Silicide) Cored Wire – Typically used for deoxidation and desulphurization. The standard specification includes Ca 28–30%, Si 55–60%, with low Al and C.
• CaFe (Calcium Iron) Cored Wire – Offers a more stable and less reactive alternative to CaSi; widely used in steel refining.
• FeTi (Ferro Titanium) Cored Wire – Mainly used for grain refinement and to tie residual nitrogen in steel.
• FeB (Ferro Boron) Cored Wire – Introduced for increasing hardenability of steels, with B content typically 18–20%.
• FeMg (Ferro Magnesium) or Pure Mg Cored Wire – Used in ductile iron manufacturing for spheroidization.

India is both a significant user and a growing exporter of cored wires. Export-grade wires such as CaSi Cored Wire (13 mm or 9 mm) and FeTi Cored Wire have established markets in Southeast Asia and the Middle East, especially from clusters in eastern and western India.

However, the Indian market does not yet manufacture all types of cored wires. Specialized grades such as Pure Calcium (Ca) Cored Wire, Barium-Aluminum Cored Wire, Sulphur Cored Wire, and REFeSi (Rare Earth Ferro Silicon) cored wires are still not widely produced domestically. These niche products require advanced filling systems and handling expertise due to their high reactivity and volatility.

This is where our company brings unmatched value. Not only do we source the most commonly used Indian-manufactured wires, we also import high-demand, non-Indian variants such as Pure Ca, BaAl, S-Cored, and RE-based Cored Wires—allowing us to offer an unmatched product portfolio. Our expertise in quality control, logistics, and end-user integration ensures consistency and cost efficiency, especially for foundries and mini-mills looking for a dependable partner who understands both global and Indian sourcing dynamics.

With the sector growing steadily, and domestic production unable to fully cater to all specialized grades, we fill a critical gap—making us the preferred choice for both standard and advanced cored wire solutions.
