70% Fe Silicon
70% Fe Silicon Description
70% Fe Silicon is an alloy of iron and silicon. Silicon increases steel hardness, tensile strength, elasticity and fluidity limits, increases oxidation resistance, and reduces energy losses. 70% Fe Silicon is smelted from quartzite (rarely quartz) in powerful ore-thermal furnaces. Ferrosilicon is used for deoxidation and alloying of steel, and rich grades are also used for the recovery of metals from oxides.

70% Fe Silicon Supplier
70% Fe Silicon for metallurgy is an alloy of iron and silicon with a minimum amount of impurities.
The main component is silicon (Si). It adds the following properties:
Elasticity is the ability to return to its original position when compressed and bent.
High resistance to corrosion. Silicon prevents oxidation of steel, preventing rusting.
Hardness and resistance to high temperatures.
70% Fe Silicon with silicon is used as a deoxidizing and alloying additive in the smelting of spring, electrical, tool, structural, heat-resistant and corrosion-resistant steel, as well as for modifying and alloying cast iron.
