Commercially, Fe-Si is distinguished by its grade and size. The Fe-Si grade is defined by the percentage of Si and trace elements contained in the product. The main characteristic is the percentage of Si contained in the ferroalloy, and the grade mainly refers to this percentage. Therefore, 75% Fe-Si contains approximately 75% Si.
The Fe-Si grade is further defined by the percentage of trace elements present in the product. "Regular grade 75% Fe-Si" indicates that the product contains the indicated percentage of Si and the recognized maximum percentage of trace elements. Other grades of Fe-Si differ from the regular grade in having stricter limits on the content of elements such as Al, titanium (Ti), and/or Ca in the ferroalloy.
Ferro silicon is also produced in grades containing controlled amounts of trace elements, with the purpose of adding them to steel or cast iron using ferrosilicon as a carrier. This type of ferrosilicon product is sometimes referred to as a "inoculant."
