Product information

MagniF standard grades

MagniF has three standard grades:

  • MagniF 10
  • MagniF 25
  • MagniF 50

MagniF 10 and 25 are available as food approved grades for the use in applications with food contact:

  • MagniF 10F
  • MagniF 25F

MagniF packaging

Our MagniF product range is available in paper sacks or big bags. Due to the product’s conditions, no bulk solution is available.

Benefits of MagniF

When you add MagniF in polymers and coatings, it provides the following properties:

Applications using MagniF

The benefits, as mentioned above, of MagniF, have a decisive part in the manufacture of a wide range of products. Our customers use MagniF for:

Providing technical and economical solutions

MagniF is the only technical or the most economical solution in, for example:

  • Metal detectability of meat protection bags and inliners for butchery boxes, that allows for detecting contaminations in packed grained meat
  • 3D-printed parts to provide a metallic touch
  • Metal detectability of moulded plastics

Dry, pure, fine-milled magnetite

MagniF is a pure and fine powder milled from the natural mineral Magnetite mined and processed at our group resources in the north of Sweden. This relation ensures a long-term, reliable source of consistent quality material.

You will find that our MagniF from the natural iron oxide Magnetite is ferri-magnetic, greyish-black in colour, and thermally and electrically conductive.

MagniF mineral origin

LKAB Minerals‘ Magnetite is mined from our own group resources. The LKAB mines are located in Kiruna and Malmberget in the northern part of Sweden. The iron ore is mined and milled at the mine site and railed to one of two ports – Luleå in Sweden or Narvik in Norway. The ports are part of the LKAB Group logistics structure. LKAB Minerals supply from these ports and strategic stocks at various locations worldwide.

MagniF toxicology

Magnetite is inert, will not rust and does not degrade with time or usage. It is ferri-magnetic and, for that reason, will be attracted by a magnet. This natural mineral can be recovered, recycled and reused repeatedly.
