What is silicon metal grade 441?

Silicon metal is a gray and shiny semiconductor metal,also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys which smelted from quartz and coke in an electric furnace.

Silicon metal grade 441, with a silicon content of 99%. The contents of iron, aluminum, and calcium are 4%, 4%, and 1%. Silicon is an essential element in steelmaking. Silicon 441 has a higher silicon content. So it can be used as an iron alloy additive in the steelmaking industry. The price of metal silicon 441 is higher than metal silicon 553, but the quality is better.

The classification of metallic silicon is usually classified according to the content of iron, aluminum and calcium, silicon metal can be divided into different grades such as 553, 441, 411, 3303, 2202, and 1101.

Silicon metal 441 grade specification：

Silicon metal 441 uses:

1. Aluminum alloy

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. Solar industry and electronics industry

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
