Silicon metal 553 is a commonly used grade. In silicon metal 553, the silicon content should reach 98.5%. The contents of iron, aluminum and calcium are 0.5%, 0.5% and 0.3% respectively.Silicon 553 and silicon 441 are mainly used in the production of aluminum ingots.Adding silicon metal with aluminum alloys makes them strong and light.
The prticle size of silicon metal 553 includes 10-50mm,50-100mm,10-100mm or other sizes as customer’s request. 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 is generally classified based on its iron, aluminum and calcium content. Silicon metal can be divided into different categories, such as silicon metal 553/441/3303/2202 and 1101.
Silicon metal 553 grades:
The chemical composition of silicon metal generally consists of silicon, iron, aluminum and calcium. Therefore, the grade of silicon metal is divided based on the three main impurities of iron, aluminum and calcium.
For example: in silicon metal grade 553, the iron, aluminum and calcium contents are 0.5%, 0.5% and 0.3%.
Commonly used grades are 553/441/3303/2202/411/421, etc. Which brand to use depends on the user's area of application and the effect they want to achieve.
1. Aluminum alloy
It can improve aluminum's already useful properties, such as castability, hardness and strength. Adding metallic silicon to aluminum alloys makes them strong and lightweight.
2. The solar industry and the electronics industry.
Silicon metal can also be used as an essential material in the solar and electronics industries. For example, it can be used in the manufacturing of solar panels, semiconductors and silicon chips.
3. production of silicone rubber, silicone resin, silicone oil, etc.
1. Silicon metal 553 comes in two forms: block and powder. Regarding the particle size, the silicon metal plant can be produced according to user requirements.
2. Silicon metal 553 is generally packaged in 1Mt bags. It can also be packaged according to user requirements.
3. The minimum order quantity of silicon metal 553 is 20-25MT (but we also accept LCL).
4. Payment terms for silicon metal 553: T/T
Delivery time of silicon metal 553: Within 5-7 days after receiving the prepayment.
