Ferro Silicon Alloy 75 Content Silver Grey Color Widely Applied In Steel Industry Deoxidation​

Ferro Silicon alloy with 75% silicon content and silver-grey color is a staple deoxidizer in the steel industry due to its powerful oxygen-scavenging ability and clean appearance reflecting low impurity levels. The high silicon concentration ensures thorough removal of dissolved oxygen in molten steel, forming silica slag that protects the metal from oxidative damage and improves internal cleanliness. This results in steels with higher toughness, better fatigue resistance, and fewer non-metallic inclusions.

The silver-grey hue signals a well-controlled production process, assuring metallurgists of consistent alloy performance. It is compatible with all major steelmaking furnaces, including electric arc, basic oxygen, and induction types, and can be added in lump or crushed forms depending on process needs. Beyond deoxidation, the alloy adjusts silicon levels in steel, influencing strength, magnetic permeability, and response to heat treatment. Steelmakers favor this material for producing high-quality carbon, alloy, and electrical steels used in transformers, motors, automotive bodies, and infrastructure projects, benefiting from both performance gains and operational simplicity.
