Ferrosilicon Powder 150 Mesh Fine Grey Material For Arc Welding Rod And Alloy Additive
Ferrosilicon powder (150 mesh) is a finely ground ferroalloy with around 45–75% silicon, depending on grade, appearing as a uniform grey powder. The fine particle size ensures rapid dissolution and homogeneous distribution in welding rod coatings and specialty alloys. | | |

- • Rapid reactivity: Small particles dissolve quickly in weld pool, contributing silicon for deoxidation and strength.
- • Uniform coating: Ensures consistent welding rod performance and slag formation.
- • Controlled composition: Low impurities help maintain weld metal integrity.
- • Acts as a deoxidizer in the weld metal, reducing oxygen‑related defects.
- • Enhances fluidity of weld pool for smoother bead formation.
- • Contributes modest silicon to improve tensile strength of weld deposit.
- • Production of self‑hardening or wear‑resistant alloys.
- • Additive in powder metallurgy blends.
