Ferro Silicon

After carbon, silicon is the most important element affecting the structure of cast irons. Silicon, pouring liquid  As it increases the fluidity of the iron, it also affects the solidification process of the alloy, as it has a significant effect on the carbon equivalent.  dissolving in the ferrite phase, increasing the ductility of the material and  It can increase strength and hardness without adversely affecting its toughness. Natural
Silicon also has a similar effect on cast steel parts.
