DESCRIPTION
FeSi 75 and FeSi 65 are two different types of ferrosilicon alloys, which are made by mixing iron and silicon.
FeSi 75 contains approximately 75% silicon and 25% iron, while FeSi 65 contains approximately 65% silicon and 35% iron. The exact composition of each alloy can vary slightly depending on the manufacturer.
Both FeSi 75 and FeSi 65 are used in a variety of industrial applications, such as in the production of steel and cast iron. They are added to the molten metal to help control the composition of the final product and to improve its properties, such as strength and durability.
FeSi 75 is typically used when a higher silicon content is desired, while FeSi 65 is used when a lower silicon content is sufficient. The choice between the two alloys will depend on the specific requirements of the application.
