Silicon metal 97, or we can also call it off grade silicon, is a model of Si metal. Main impurity of Off-Grade Silicon 97 is similar to other silicon metals, including elements such as iron, aluminum and calcium. The main use of this metallic silicon is as an additive to non-ferrous alloys, replacing other grades silicons. And, it is widely used in many fields.
Usage of Off-Grade Silicon 97
As an alloy additive is one of the main uses of Off Grade Silicon Metal 97. Adding silicon and magnesium ingot to aluminum alloys can significantly improve the strength, hardness and wear resistance of the alloy. Moreover, it helps to improve casting and welding properties. Especially among aluminum alloys such as Si-Al and Mg-Al alloys and duralumin. The dosage of metal silicon 97 is the most prominent. In addition, it is also a good deoxidizer, reducing agent, semiconductor material, etc.
The price of Si 97 is more affordable than other models such as silicon metal 553 and silicon metal 441. According to Chinese national standards, metallic silicon has multiple models, and metallic silicon 97 has a silicon content of more than 97%. In places such as Russia and Germany, there are similar standards, with silicon content of 96% to 99% and 97% to 99% respectively.
In the production process of Off-Grade Silicon 97 , if the raw material particle size is too large, unreacted silica may enter the liquid silicon, increase the amount of slag, reduce product recovery rate, increase energy consumption, thereby affecting the quality of metallic silicon.
Therefore, it is crucial to choose professional off grade silicon manufacturers and suppliers.
