MAGNETS ARE EVERYWHERE Ranging from very small magnets in sensor applications and cell phones to big magnets in the aviation industry, magnets truly are everywhere. Permanent magnets contribute to many aspects of modern life, industry and transportation. Permanent magnets are used in hybrid car motors and renewable energy production, which makes magnets an important resource for a more sustainable future. We are the leading supplier of NdFeB permanent magnets for renewable energy applications in Europe and participating in the fight against climate change.

FOCUSING ON THE PRODUCTION OF BIG MAGNETS Neorem Magnets can offer both sintered NdFeB magnets and magnet assemblies. All our NdFeB material is manufactured at our factory in Ulvila, Finland. We are focused on the production of big magnets, radial and axial flux machine magnets and very small magnets for sensor applications. Our coating options include nickel, tin, Al, TiN and various epoxies.

MAGNET ASSEMBLIES Magnet assemblies, for example magnet pole elements for wind turbine generators, are manufactured at our automated factories in Finland and in China. We have all the special equipment needed for magnetizing, handling and measuring large-scale magnet systems. // Designed with experience // Flexibility in design // Profound magnetism knowledge

PERMANENT MAGNETS The normal manufacturing method used by Neorem Magnets is axial pressing, which is the most cost effective solution. However, all our grades can also be transversally pressed. The transversal pressing gives a higher remanence, but creates some restrictions regarding the magnet’s shape. // Multiple magnet choices

Special products and services In addition to NdFeB permanent magnets, we can supply SmCo, AlNiCo and ferrite magnets sourced and quality controlled by our subsidiary in China. Furthermore, we can offer technical and consulting services related to permanent magnets and their applications.

Multiple magnet choices Neorem Magnets has also developed new grades with low heavy rare earth metal content. These magnet alloys are available from various sources. Low heavy rare earth magnets are suitable for applications where relatively high coercivity is needed, but which are extremely price sensitive for magnets.


MAGNET ALLOY Hydrogen is introduced to the alloy and removed by heat the alloy becomes brittle and can be easily crushed.

MAGNETIZING & PACKAGING The final products are magnetized and packed ready for delivery.

JET MILLING Grinding is accomplished in a jetmill utilizing high pressure gas flow. The alloy is ground against itself, and the particles become single crystals.

STATE-OF-THE-ART PROCESSING Our magnets are produced using powder metallurgical methods by die pressing and sintering. With our well refined quality process, we are able to produce excellent and consistent magnetic properties. The process starts from the hydrogen decrepitation and jet milling of the magnet alloy. The resulting powder is then compressed into the wanted shape and at the same time its particles are aligned using a magnetic field. The compacted blocks are then sintered and machined into the final dimensions before coating and magnetizing. Neorem Magnets produces sintered NdFeB permanent magnets in all forms with various coatings (passivated, Ni, Sn, Al, TiN, epoxies)

Perfect touch Quality inspection at each manufacturing step together with highly automated production provides a stable and well-controlled process, high yield, and homogenous and consistent magnet properties.

500 SERIES

700 SERIES

800 SERIES

NEOREM 500 series general grades with moderate magnetic and corrosion properties. Available in any shape and size.

NEOREM 700 series grades are characterized by improved remanence, coercivity and corrosion resistivity.

NEOREM 800 series grades are suitable for most demanding applications with extreme magnetic properties.
