Silicon Metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. It is a product made by smelting quartz and coke in an electric furnace. The main element silicon content is about 98%, and the remaining impurities are iron and aluminum, Calcium, etc.Silicon metal is a silver-gray or dark gray powder with a metallic luster, and high melting point, good heat resistance, high resistivity, and superior oxidation resistance, it's called "industrial glutamate".

2. Silicon powder is regarded as an alloy additive, improving steel hardenability in the metallurgy and foundry industry.

1. Used in aluminum, silicon metal is an additive to aluminum alloys, silicon is used to increase the fluidity and tenacity of Aluminum and its alloys, which enjoy good castability and weldability accordingly.
