In the metallurgical casting industry, industrial silicon metal is an additive for nonferrous alloys and alloying agents in silicon steel in order to greatly enhance the hardness of the finished steel products. Silicon granules are also used as a metal reducing agent for modern ceramic alloys, providing additional hardness and heat resistance.
