No matter where your daily life takes you, you will encounter products that contain manganese alloys from Eramet Norway. The processing plants in Norway have unique metallurgical expertise that is exported through our products to countries all around the world.

Eramet Norway supplies the world’s steel producers with a complete range of high-quality manganese alloys. In our processing plants in Norway, raw manganese is refined and processed into ferromanganese and silicomanganese. These additive ingredients comprise 1–10 per cent of the composition of steel, graded by quality.




Just as the body’s bone structure needs calcium for strength, manganese is necessary to make steel ductile and durable. For one tonne of steel, about 10 kilograms of manganese is used.

Great potential for growth

Nearly 90 per cent of the world’s total manganese alloy production goes into the production of stainless steel, steel for the construction, energy and transport sectors, and the tool industry, and special steel produced for the aeronautics and aerospace industries. The construction market alone accounts for more than half the steel used worldwide. The potential for growth in this sector will remain strong in the years ahead. This growth is primarily due to urbanization and industrialization in the growth markets of China and India.

The automobile industry and production of stainless steel are the major market segments for Eramet Norway’s refined products.

100 per cent export to the international steel market

Eramet Norway exports all its production of manganese alloys, primarily to Europe and North America. The processing plants transport 98 per cent of their production by ship and the remaining percentage by road and rail.



Manganese is a hard metallic element (chemical symbol Mn, atomic number 25), a steel-grey metal. Manganese – invisible to the naked eye, but indispensable

Ferromanganese (from ferro-, meaning iron): alloys which, in addition to iron, contain up to about 80 per cent manganese and carbon in amounts ranging from about 7 per cent down to 0.5 per cent.

Silicomanganese consists mainly of manganese (up to 70 per cent), silicon (up to 30 per cent), small amounts of carbon, and the remainder iron.
