Steelmaking Silicon Metal 421/553/97 Lump / Granule / Powder

What is silicon metal

Silicon is a non-metallic element, gray, hard and brittle, with a content of about 26% of the earth's crust. Metal silicon (lump & powder), is also known as crystalline silicon or industrial silicon. It is generally used as an iron-based alloy additive.

Metal silicon can be divided into metallurgical grade and chemical grade.

Silicon metal grades

The chemical composition of metallic silicon is generally silicon, ferro, aluminum, and calcium. Therefore, the grade of metal silicon is divided according to the three main impurity contents of iron, aluminum and calcium. For example:

In the metal silicon grade 553, the contents of ferro, aluminum, and calcium are 0.5%, 0.5%, and 0.3%.

Commonly used grades are 553/441/3303/2202/411/421 and so on. What brand should be used specifically depends on what field the user is using and what effect he wants to achieve.

Some tips for silicon metal buyers

1. Metal silicon has two shapes of block and powder. About the particle size, the metal silicon factory can be produced according to the needs of users.

2. The common package is 1Mt/Bag. It can also be packaged according to the user's requirements.

3. The minimum order quantity is 20-24MT (But we also accept LCL).

Silicon metal uses

1. Aluminum alloy

It 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.
