About Ferrosilicon

The global ferrosilicon market is undergoing a technical metamorphosis as the transition toward electric arc furnace (EAF) technology and high-purity alloy steel production intensifies the demand for 75% grade alloys with precise trace-element control. This shift is particularly evident in the increasing adoption of ul...
