Ferrosilicon
An alloy of iron and silicon used primarily as a deoxidizer and alloying element in the production of steel and cast iron.
Overview
Ferrosilicon is essential in automotive metallurgy for deoxidizing molten steel and as an inoculant in the production of ductile iron. It enhances the strength, hardness, and magnetic properties of various automotive alloys, particularly electrical steel used in EV motors. Its composition typically ranges from 15% to 90% silicon, with the remainder being iron and trace elements. In manufacturing, it is critical for ensuring the structural integrity of engine and chassis components.
