Rare-earth magnets NdFeB Rare-earth magnets NdFeB (neodymium-iron-borron) are currently the strongest permanent magnets. The original material is produced by sintering and then cut to resulting shapes in accordance with the dimensional requirements of the customer. Thanks to this production process, it is possible to supply a wide range of various shapes.

Neodymium magnet prism with a hole for screws with embedded headsWe broadened our offer of neodymium magnets with new articles. These are magnets including a screw hole (countersunk-head bolt), in cubic and cylindrical shapes. The magnets may be screwed onto non-metallic surfaces.

Neodymium self-sticking magnet prismAs another choice, magnets with self-adhesive labels, also in cubic and cylindrical shapes, are considered. These magnets are to be simply stuck onto non-metallic surfaces. Due to a strong 3M self-adhesive layer, they hold firmly. We offer these magnets also as pairs where the surfaces without the self-adhesive label attract to each other.

Surface treatment of NdFeB magnets

Rare-earth neodymium magnets are very prone to corrosion, therefore, in principle, surface treatment is used in form of nickel plating (10-20 µm), zinc plating (5-10 µm), epoxy resin plating (20-30 µm) or passivation.
