Ferroalloys
Ferroalloys Business
With our two major production bases in Tokushima and Kashima, we harness our proven technology and time-tested techniques to provide our customers with stable supplies of high-quality manganese.
Our portfolio includes not only ferromanganese but also other ferroalloy products. These quality products have been well received by our customers, sustaining Nippon Denko’s reputation as a leading manufacturer of ferroalloys.
In addition our Tokushima Plants are producing diverse fertilizers indispensable for soil improvement, by making use of the soil-improving properties of by-products obtained from ferroalloy production.

SLP ferromanganese
- Feature
- Boasts higher manganese content than standard ferromanganese with lower carbon and phosphorus contents
- Application
- Used mainly as an additive for high-quality steels
Ferrosilicomanganese
- Feature
- A composite alloy mainly made of silicon and manganese
- Application
- Used as a manganese- and silicon-based additive, deoxidizing agent or desulfurizing agent for molten steels
Ferrosilicon
- Feature
- Used broadly for steels in large quantities and generate a large amount of heat during oxidation without substantially lowering the molten steels temperature
- Application
- Used as a deoxidizing agent for steel production, silicon additive or casting adhesive
Ferrovanadium
- Feature
- Improves the strength of steel, effectiveness of heat treatments and weldability of steels
- Application
- Used as vanadium additive for tool steels, heat-resistant steels, high-strength low-alloy steels and cast metals
High-carbon ferrochromium
- Feature
- Used in large quantity as a chromium additive for stainless steels
- Application
- Used as chromium additives for steels such as stainless steel, alloyed steel and cast steel
Ferroniobium
- Feature
- Improves mechanical properties of steels in the same way as vanadium and helps to reduce low-temperature brittleness
- Application
- Used as a niobium additive for stainless steels, high-tensile steels, heat-resistant steels, nickel-based alloys and other special steels; permanent magnets
