Silicon metal is a non-ferrous alloy product that is gray, hard and fragile. According to its use, there are chemical silicon metal and industrial silicon. Nowadays industrial silicon is widely used in aluminum industry, steelmaking, iron-based alloy additives, etc.
High carbon silicon, also known as silicon carbon alloy, or High Carnon Ferrosilicon. This product is a by-product of the production of metal silicon. The main content is composed of silicon and carbon.silicon content is usually between 40-70% and carbon content is 10-25%. Other contents are: silica, phosphorus, sulfur, etc.
Ferro silicon is a gray iron alloy composed of iron and silicon. According to the content of Si, Fe, Al, etc., there are different grades. The most widely used are 75% ferrosilicon and 72% ferro silicon.
