Silicon Metal 3303

Product
Description

1.Silicon Metal is a very important industrial product can be used in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), and silicon optoelectronic device and many other industries. It's known as the "salt" of modern industries. Metal silicon is made from quartz and coke in electric heating furnace smelting products.

2.The chemical composition of metal silicon is generally silicon, iron, aluminum and calcium. Therefore, the grade of metal silicon is divided according to the content of three main impurities: iron, aluminum and calcium. For example：In metal silicon grade 3303, the content of iron, aluminum and calcium are 0.3%, 0.3% and 0.03% respectively.

3.The classification of metal silicon is usually classified according to the content of iron, aluminum and calcium. Metal silicon can be divided into different grades such as metal silicon 553/441/3303/2202 and 1101.

APPLICATION

1. Aluminum alloy

It can improve properties that aluminum is already useful for, such as castability, hardness and strength. Adding silicon metal to aluminum alloys makes them strong and lightweight.Therefore, they are increasingly used in the automotive industry. For replacement of heavier cast iron parts. Auto parts such as engine blocks and tire rims are the most common cast aluminum silicon parts.

2. Solar industry and electronics industry.

Silicon metal can also be used as a basic material in the solar and electronics industries. For example, it can be used to make solar panels, semiconductors and silicon chips.

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