Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon metal is a product smelted by quartz and coke in an electric heating furnace. The content of the main component silicon is about 98% (in recent years, the silicon content of 99.99% is also included in metal silicon), and the remaining impurities are iron and aluminum、 calcium、etc.

It is divided into various specifications due to different uses. According to statistics, in 1985, the world consumed about 500,000 tons of metal silicon, of which about 60% was used for aluminum alloys, less than 30% was used for organic silicon, about 3% was used for semiconductors, and the rest was used for Steel smelting and precision ceramics, etc.

Silicon metal uses:

Silicon metal 441 uses:

1. Silicon metal is mainly used in aluminum alloys

Silicon metal 441 can improve the already useful properties of aluminum such as castability, hardness and strength. Adding silicon metal to aluminium alloys makes them strong and light.

So, they are increasingly used in the automotive industry. Used to replace heavier cast iron parts. Automotive parts such as engine blocks and tire rims are the most common cast aluminum silicon parts.

2. Silicon metal is mainly used in solar energy and electronics

Silicon metal can also be used as essential material in the solar and electronics industries. For examples, it can be used in the manufacture of solar panels, semi-conductors and silicon chips.

3.Production of silicone rubber, silicone resin, silicone oil, etc

The above is the use of metal silicon shared by metal silicon manufacturers for you, I hope it can help you!
