Silicon metal 97 grade refers to a kind of silicon metal with a silicon content of about 97% in metallic silicon. Silicon Metal, also known as metal silicon or industrial silicon. It is a product made of quartz and coke smelted in electric furnace.

Metal Silicon 97 is an main additive for non-iron-based alloys. It can improve the performance and characteristics of the alloy and increase its strength, hardness and wear resistance. In addition, silicon metal 97 can also improve the corrosion resistance and high temperature resistance of the alloy. In short, it has a wide range of applications in the aluminum alloy industry.

What calls for special attention is that the main feature of silicon metal 97 is that the content of silicon element is around 97%. The remaining impurities include iron, aluminum, calcium, etc. In comparison, silicon metal with higher silicon content, such as silicon metal 1101, refers to industrial silicon with a silicon content of approximately 99.8%. It is a material in semiconductor manufacturing and solar panels and other fields.

97 silicon also have another name: Off grade silicon metal. In the past, the Si content of this product was only more than 93%, and later gradually increased to 95%, 96%, and 97%. The current silicon metal 97 can also be divided into several models, depending on the iron and calcium content.
