When you choose ferrosilicon products you can refer to these aspects:
Chemical composition and physical properties
The main components of ferrosilicon are silicon and iron, and the silicon content is usually between 72% and 75%. In addition, the impurity content of ferrosilicon such as calcium oxide and magnesium oxide will also affect its quality. The silicon content of high quality ferrosilicon should meet the relevant standards and the impurity content is low.
Appearance
The appearance of high-quality ferrosilicon should be dark grey, with bright and uniform metallic luster, smooth surface without cracks, no oxidation. If the surface of ferrosilicon is rough, cracked or oxidised, there may be quality problems.
Application Scenario
Ferrosilicon has unique advantages in steelmaking and other industrial applications. High silicon content ferrosilicon such as 75A ferrosilicon has high density, high strength, good ductility and corrosion resistance, and is suitable for use as a deoxidiser and alloying element incorporator.
Brands and suppliers
Choosing reputable brands and reliable suppliers can ensure the quality and stability of ferrosilicon. Quality brands usually have strict quality control and stable supply capacity.
