Silicon grades 553 & 441

The classification of silicon metal is usually based on the content of iron, aluminum and calcium, the three main impurities contained in the composition of silicon metal.According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.

Silicon metalis our main products, the main grades of silicon metal are smelting 97 silicon metal, silicon metal 553 and 441 and 3303,2202.1101 annual output of 280,000-36,000 tons, focusing on the production and wholesale of silicon metal.
