Ferrosilicon Powder Ultra Fine 200 Mesh For Brazing Filler And Special Steel Refining

Ultra-fine Ferrosilicon powder with a 200-mesh particle size is a high-performance material used in brazing filler production and special steel refining. The extremely fine grind ensures maximum reactivity and uniform dispersion, which is critical when adding alloying elements in delicate processes.

In brazing, the powder acts as a silicon source, improving wetting and flow characteristics of the filler metal, resulting in strong, leak-free joints in components made of dissimilar metals. In special steel refining, it serves as a precise deoxidizer and alloying agent, enabling tight control over final steel chemistry, especially for stainless, tool, and high-temperature grades.

The fine particle size also reduces reaction time, enhancing process efficiency. Because of its high surface area, the powder must be handled with care to prevent atmospheric moisture uptake. Metallurgists and fabricators choose this ultra-fine FeSi powder for applications demanding exceptional purity, accuracy, and performance, such as in aerospace, nuclear, and advanced manufacturing sectors.
