Silicon metal 97 is the smelting material that is widely used in the smelting of aluminum ingot and special steel at present. It is a kind of good non-iron base alloy additive. The content of silicon metal 97 produced by zheng is as high as 99.99%.

The main component of metallic silicon is silicon, so it has similar properties to silicon. The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties. The classification of metallic silicon is usually based on the content of the three main impurities of iron, aluminum, and calcium contained in the metallic silicon component. According to the content of iron, aluminum, and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.
