Description of Ferrosilicon Alloy:
Ferrosilicon is an alloy of iron and silicon, it is often used as a deoxidizer in steelmaking, and can also be used as an alloying element additive. It is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. It is used as inoculant and nodulizer in the iron industry. And it is used as reducing agent in ferroalloy production and chemical industry.
We have high silicon ferrosilicon, ordinary ferrosilicon and low alumina ferrosilicon and high purity ferrosilicon.
