Fe Silicon 75% is also used in the manufacture of silicon, corrosion- and high-temperature-resistant iron-silicon alloys, and silicon steel for the cores of electric motors and transformers. In the manufacture of cast iron, 75% Fesi Ferrosilicon is used to incubate iron to accelerate graphitization.

Fe Silicon generally contains 70% to 75% silicon, which gives ferrosilicon excellent silicide properties.
75% Fe Si Foundry Grade has low hysteresis loss, which means that it can reduce energy loss in AC electromagnetic fields.
