1,Low silicon ferrosilicon:15% and 45%

2,Medium silicon ferrosilicon: 45% and 75%

3,High silicon ferrosilicon: 75% and 90%

1,Electrical ferrosilicon: Silicon content is higher, usually above 75%, used to make electrical steel and motor materials, with excellent magnetic properties.

2,Casting ferrosilicon: Used for modification and deoxidation in the casting process, the silicon content is usually between 45% and 75%.

3,Ferrosilicon for steelmaking: used as a deoxidizer and alloy additive in steelmaking, with a wide range of silicon content, from 15% to 75%.

1,Ordinary ferrosilicon:

2,Ferrosilicon for ductile iron:

3,Special ferrosilicon: used for special applications, such as the production of high-silicon steel or alloys, with specific silicon content and performance requirements.

1,: The size is usually less than 1 mm, suitable for applications that require rapid dissolution.

2,: The size is between 1 and 3 mm, suitable for general industrial applications.

3,: The size is above 3 mm, used for applications that require slow dissolution or have special requirements for size.
