Physical property of silicon carbon alloy

Silicon carbon alloy, also known as high carbon silicon, is a new type of alloy for Bessemer. Its main components include silicon (Si) and carbon (C), while also containing a small amount of aluminum (Al), calcium (Ca), iron (Fe) and other elements, as well as trace impurities such as manganese (Mn), phosphorus (P), sulfur (S) and so on. The content of silicon is usually between 50% and 70%, while the content of carbon is between 10% and 30%. The higher the silicon content, the wider the application range of silicon carbon alloy, but at the same time the price of the alloy will be higher.
 

Physical property

Density

The density of silicon carbon alloy is smaller than that of steel, but the hardness is higher than that of steel, showing the characteristics of high strength, high hardness and high toughness.

Electrical and thermal conductivity

The electrical and thermal conductivity of silicon carbon alloy is also better than that of steel, which makes it a significant advantage in the manufacture of carbide cutting tools, automated mechanical parts and high speed steel.

Fusing point

The melting point of silicon carbon alloy is high, reaching about 1680℃, so it can work stably in high temperature and high pressure environment, suitable for the manufacture of high temperature resistant materials and superalloys.
