Silicon Metal 553

Metal silicon 553, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys.
​​​​​​​The main component silicon content is about 98.5%
The contents of Fe, Al and Ca were 0.5%, 0.5% and 0.3%, respectively.
Metal silicon 553 generally has a diameter of 10-50mm, 10-80mm, 10-100mm or other sizes according to customer requirements.
Product Description
Silicon metal classification:
 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 silicon metal 553/441/3303/2202 and 1101.

Silicon metal 553 uses:  Aluminium ingot factory/aluminium manufacturer
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.
3.Production of silicone rubber, silicone resin, silicone oil, etc.

Some tips for silicon metal 553 buyers:
1. Metal silicon 553 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. Silicon metal 553 the common package is 1Mt/Bag. It can also be packaged according to the user’s requirements.
