Appearance: The appearance of ferrosilicon is metallic bread color, without powder or slag.
Chemical composition: In addition to Si and Fe, ferrosilicon also contains elements such as Mn, Cr, P, S, and C.
Melting point: 72 # -80 # silicon iron melting point 1290 ° C-1360 ° C, 75 # silicon iron melting point 1300 ° C.
Density: The density of ferrosilicon depends on the content of silicon in the ferrosilicon, and its density decreases with the increase of silicon content in the ferrosilicon alloy. The density of 75 # silicon iron is 3270kg/m ³.
