Permanent magnets

MULTIPLE MAGNET CHOICES

Neorem Magnets has three standard series of sintered NdFeB magnet grades:

NEOREM 500 series grades are available for applications that can be used under normal ambient conditions without additional surface coating.
NEOREM 700 series grades are characterized by high remanence and corrosion resistivity.
NEOREM 800 series grades are suitable for most demanding applications with extreme magnetic properties.
Special magnet grades with tailor-made properties are constantly produced.

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 for the magnet shape.

Neorem Magnets has developed also new grades with low heavy rare earth metal content. These magnets are suitable for applications, where relatively high coercivity is needed, but which are extremely price sensitive for magnets.
