Our strengths, defining characteristics, and vision
The Nippon Denko Group traces its origins to producing ferroalloys to add to iron to achieve the desired properties, and we have developed continuously since then by finding applications for the roots of our original business-electric furnaces and metallurgical technology-in a wide range of fields. We currently help society advance through our four core businesses: Ferroalloys, Functional Materials, Environment, and Electric Power.
Electric furnacesFerroalloys are produced by causing metallic ores to react with coke and other reducing agents, a process that requires heat energy, which is generally provided by electric furnaces.
1925
The Nippon Denko Group traces its origins to producing ferroalloys using electric furnaces that run on hydropower. We have manufactured manganese ferroalloys from the start, and our high quality has earned the customers’ trust and made us Japan’s top supplier.
1935
In the beginning, our electric furnaces ran on hydropower. We are promoting initiatives to supply clean energy, and in 2014, our Horomangawa Hydroelectric Power Plants in Hokkaido were approved for the Japanese government’s Feed-In Tariff (FIT) system for renewable energy.
1960
We applied the technology to operate our ferroalloy-producing electric furnaces in other fields to branch out into the Functional Materials business. We currently produce a wide array of high-performance materials for electronic parts, batteries, and more.
1973
Factories are required to remove metals and chemical compounds from their wastewater to conserve the environment. We market our know-how in this area in the form of Aqua Solutions business to contribute to recycling water resources and environmental conservation.
2002
At our Kashima Plant electric furnaces were originally used to produce ferroalloys. We have since channeled the excess capacity into recycling incineration ash, and have even installed new electric furnaces especially for this purpose to help achieve a recycling-based society.
Aiming to be a company on a constant quest for a better future by supporting people’s lives through materials and the environment, we strive to realize this vision by providing products, technologies, and services that help achieve carbon neutrality and reduce environmental impact.
Ferroalloys are an important component of most iron products. They make steel stronger as well as more resistant to corrosion, etc. and improve other properties of nearly all iron products.
Ferroalloys are omnipresent in all kinds of iron products from buildings, bridges, and automobiles to petroleum and gas pipelines. In this way, the ferroalloys we produce are an essential part of the infrastructure supporting your daily life.
Pertama Ferroalloys Sdn. Bhd., a Malaysian affiliate (25% stake). secures competitive green electricity from the largest hydropower facility in Southeast Asia (Bakun Dam, 2,400 MW) for electricity-intensive ferroalloy production.
We produce high-performance, high-quality materials for batteries and electronic parts on the strength of our metallurgical and powder technologies.
Our functional materials are used in a number of advanced materials, including capacitors and other electronic parts, and batteries for hybrid and electric vehicles, thus helping create a sustainable society.
Zirconium oxide is used to make the ceramic capacitors in the electrical circuits of digital home appliances, computers, and other digital devices.
Most waste generated by households is first incinerated and then disposed of in landfills without being recycled.
We use electric furnaces to melt and solidify that incineration ash for recycling, thereby achieving a perfect recycling and contributing to a sound material-cycle society (circular economy).

We lease and sell wastewater treatment equipment that adsorb and recover heavy metals and other substances from wastewater and also sell Pure Water Production System required to manufacture hydrogen, all to help reduce environmental impact and accelerate the shift to a hydrogen-based society.
Wastewater Treatment Equipment
| Demineralizers for Ene-Farm (home-use fuel cells) |
Ene-Farm (home-use fuel cells) are gaining popularity as an alternative energy source. The fuel cells generate electricity from hydrogen extracted from gas, a process that requires purified water.

| Pure Water Production System for onsite hydrogen stations |
Commercial hydrogen stations began appearing in 2013. In response, we started selling our Pure Water Production System in earnest. The next year, Toyota Motor released its first fuel cell vehicle, and the installation of hydrogen stations continued. For some background, the hydrogen station unveiled at Expo 2005 in Aichi featured MR PACK, and we captured the top share in Japan for onsite hydrogen stations.
