Silicon Metal 551
Silicon metal: 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.
Grade: Silicon metal grade 551, with a silicon content of 99%. The contents of iron, aluminum, and calcium are 0.5%, 0.5%, and 0.1%.
Specifications: Silicon metal 551 generally the diameter is 10-50mm,50-100mm,10-100mm or other sizes as customer’s request.
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 553, 441, 411, 3303, 2202, and 1101.
Application: Aluminium ingot factory/aluminium manufacturer
APPLICATION
Silicon metal 551 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.
Silicon metal 551 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.
3.Production of silicone rubber, silicone resin, silicone oil, etc.
