Description: Silicon Metal is also called industrial silicon or crystalline silicon. It has high melting points, good heat resistance and high resistivity. It is used to manufacture steel, solar cells, and microchips. Also used to produce silicone and silane, which are in turn used to make lubricants, water repellents, resins, cosmetics, hair shampoos and toothpastes. Size: 10-100mm or customized Packing: 1mt big bags or as per buyer's requirement. 1,Silicon metal 441 What is silicon metal grade 441? Silicon metal grade 441 has a silicon content of 99%. The contents of iron, aluminum, and calcium are 4%, 4%, and 1%. Silicon metal 441 specifications: Silicon metal 441 generally the diameter is 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 is smelted from quartz and coke in an electric furnace. 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. 2,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.
