Silicon Metal

Metal silicon is mainly used as an additive for non-ferrous alloys.

Metal silicon, also known as crystalline silicon or industrial silicon

The main component silicon content is about 98%

The content of iron and calcium was 0.8% and 0.1%, respectively.

Metal silicon particle size is 10-50mm , 10-80mm , 10-100mm or other sizes as customer’s request.

Application:

Silicon metal application: aluminum ingot factory/aluminum material manufacturer
1. Aluminum alloy
It can improve the existing properties of aluminum 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.
