Silicon metal is used, among other things, as an aluminium alloyant; it is also employed in the chemicals industry for the manufacture of siloxanes and silicones. Silicon metal can also be used as essential material in the electronics and solar industries (silicon chips, semi-conductors,solar panels). It can improve the already useful properties of aluminum such as castability, hardness and strength. Adding silicon metal to aluminium alloys makes them light and strong. So, they are increasingly used in the automotive industry. Used to replace heavier cast iron parts. Automotive parts such as engine blocks and tire rims are the most common cast aluminum silicon parts.
