Scientific name (alias): ferrosilicon is also called ferrosilicon.
Ferrosilicon model: 65#, 72#, 75#
Ferrosilicon 75\1) national standard 75\refers to actual silicon ≥ 72%; (2) Hard ferrosilicon refers to actual silicon ≥ 75%; Ferrosilicon 65# refers to silicon content above 65%; Low aluminum ferrosilicon: usually refers to the aluminum content in ferrosilicon below 1.0. According to different requirements of customers, it can reach below 0.5, 0.2, 0.1 and so on.
Status: natural block with thickness of about 100mm. (whether there are cracks on the appearance, whether the color fades by hand, whether the knocking sound is crisp, whether the thickness cross section is gray white, with pores)
Packing: in bulk or ton bags.
Main producing areas: Ningxia, Inner Mongolia, Qinghai, Gansu, Sichuan and Henan
Precautions: ferrosilicon is afraid of moisture. Natural blocks are easy to pulverize in case of water, and the silicon content decreases accordingly.
