Properties of High Carbon Silicon

High carbon silicon, or carbon silicon alloy, are alloy materials made primarily from silicon and carbon. Due to their physical and chemical properties, they are widely used in many fields.

First, regarding physical properties, high carbon silicon have some remarkable properties. Their density is smaller than that of steel, but their hardness is higher than that of steel, giving them high strength, high hardness, and high toughness. In addition, the electrical and thermal conductivity of silicon carbon alloys is superior to that of steel. These physical properties make silicon carbon alloys a remarkable advantage in the manufacture of hard alloy cutting tools, automated machine parts, and high-speed steels.

Silicon carbon alloys have excellent antioxidant and corrosion resistance, and they remain stable at high temperatures. They also have a low coefficient of expansion and good thermal stability. These properties allow silicon carbon alloys to operate and exist stably in a variety of media and are widely used in industries such as metallurgy, chemical industry, electronics, and semiconductor.

Of particular note is the important role silicon carbon alloys play in the steel industry. It is used as an alloying material in the deoxidizing alloying process in converter smelting and, due to its stable effect, can be used as an alternative to ferrosilicon, silicon carbide, and carburizing materials. This reduces the amount of deoxidizing agents used. Silicon carbon alloys improve the quality of steel water, enhance product quality, improve product performance, and reduce steelmaking costs and increase economic benefits through reduced alloy additions.
