Ferrosilicon (FeSi)
Ferrosilicon (FeSi) is an alloy of iron and silicon that is produced in an electric arc furnace by reducing silica (SiO₂) with coke, coal, or semi-coke in the presence of iron. It is mainly used in steelmaking.
Applications
Ferrosilicon is essential in steelmaking as a deoxidizer and alloying agent, improving strength and hardness. In cast iron production, it acts as an inoculant to enhance graphitization and mechanical properties. It is also a key material for producing ferroalloys such as MgFeSi and is used in the Pidgeon process for magnesium. Additionally, ferrosilicon supplies silicon for silicon steels, foundry applications, and serves as a heat-energy additive in various metallurgical processes.

About us:
The company was established in 2021 with the objective of strengthening the nation’s industrial supply chain and delivering reliable, high-quality ferrosilicon and alloy products to the steel sector. In 2024, the company expanded its operations by forming structured partnerships with reputable ferrosilicon manufacturers, securing a stable annual supply capacity of 12,000 tons.
In 2025, the company consolidated its activities by establishing a dedicated logistics and distribution center designed to support an annual handling capacity of 12,000 tons of ferrosilicon and 4,000 tons of microsilica powder. The site also includes designated space for future ferroalloy-related development projects. The inauguration ceremony was attended by national and provincial officials.
Supported by a skilled technical and commercial team, the company achieved 90% of its planned distribution capacity during its first year of operation and reached full capacity in the following year. Reflecting its strategic growth and evolving business focus.
