Cored Wires
Essentially used for grain refinement, cored wires are made with Iron Powder which is used as a filler material for metallurgical cored wire application along with Calcium & other additives. A high-density, low oxygen powder is preferred for this application.

As a leading manufacturer of high-quality iron and metal powders, we understand the critical role raw materials play in shaping the performance of finished products. One of the most important applications of our iron powders is in the production of cored wires—a vital consumable in steelmaking, foundries, and other metallurgical operations.
What Are Cored Wires?
Cored wires are composite materials where a metallic sheath (usually mild steel) is filled with a core material such as alloying elements, fluxes, or refining agents. During steel production, these wires are injected into molten metal to deliver precise amounts of additives, improving steel quality and refining its composition.
Role of Iron Powder in Cored Wires
Iron powder serves as a filler, carrier, and performance enhancer in various types of cored wires. Its inclusion ensures optimal wire density, stable feeding, and controlled dissolution in molten steel. Some key contributions include:
-
Improved Density and Balance
Iron powder increases the packing density of cored wires, ensuring uniform filling and smooth feeding during injection. -
Efficient Alloying and Refining
By acting as a carrier medium, iron powder enhances the controlled release of alloying elements like calcium, carbon, or other additives into the molten bath. -
Thermal and Chemical Stability
High-purity iron powder withstands high-temperature environments, ensuring consistent performance in demanding metallurgical applications. -
Versatility Across Wire Types
Whether used in calcium-silicon wires, carbon wires, or specialty alloy wires, iron powder adapts easily, supporting a wide range of metallurgical needs.
Benefits for Cored Wire Manufacturers
By choosing the right iron powder, cored wire manufacturers can achieve:
-
Consistent quality and reliable performance of the wires.
-
Enhanced productivity, with smoother feeding and reduced wire breakage.
-
Cost-effectiveness, as optimized powder properties reduce waste and improve yield.
-
Customization, where specific particle size distributions and purities are tailored to meet customer requirements.
