Ferro Silicon 75 (FeSi 75) is a high-purity ferroalloy composed of approximately 75% silicon and 25% iron. Produced through smelting quartz, coke, and steel scrap in an electric arc furnace, this grade of ferrosilicon is widely recognized for its powerful deoxidizing and alloying capabilities. As one of the most commonly used ferroalloys in steelmaking and foundry applications, Ferro Silicon 75 plays a critical role in enhancing the quality and efficiency of industrial metallurgical processes.
