Organic silicon and aluminum alloy

Organic silicon is one of the main consumer areas of industrial silicon in my country. In recent years, with the rapid development of industries such as construction, electronic appliances, electric power and new energy, textiles, daily chemicals and medical care, the demand for organic silicon products has continued to grow, thus driving the demand for industrial silicon. Polysilicon is the fastest growing area of ​​industrial silicon consumption in my country in recent years. With the rapid development of the photovoltaic industry, the demand for polysilicon has increased significantly, making it the largest consumer area of ​​industrial silicon.

Aluminum alloy is the third largest consumer area of ​​industrial silicon in my country. Adding silicon to aluminum alloy can improve its high-temperature fluidity, reduce shrinkage and thermal tendency, and improve wear resistance and other properties, so it is widely used in industries such as automobiles and machinery manufacturing. In 2023, as the global photovoltaic installed capacity continued to grow at a high speed, the polysilicon industry expanded production significantly, which greatly boosted the demand for industrial silicon. China's domestic apparent consumption of industrial silicon was 3.1892 million tons, a year-on-year increase of 20.39%, and has achieved positive growth for four consecutive years. Among the downstream demand for industrial silicon, polysilicon, organic silicon and aluminum alloy fields consume a large amount of industrial silicon. Among them, in 2023, polysilicon consumed 1.825 million tons of industrial silicon, significantly ahead of other consumption areas, accounting for 53%, an increase of 14 percentage points from 2022; organosilicon consumed 925,000 tons of industrial silicon, accounting for 27%, a decrease of 9 percentage points; aluminum alloy consumed 652,000 tons of industrial silicon, accounting for 19%, a decrease of 4 percentage points.
