Permanent neodymium magnets

on the base of Neodymium-Iron-Boron (Nd-Fe-B) alloys

(TU U 21174514.001-96)

 

Permanent neodymium magnets on the base of Neodymium-Iron-Boron alloy are the most powerful permanent magnets in the world.

 

Polus-N have a varied range of magnets to suit many different applications. Here you can browse through the range of magnets that we can supply and find out more about how they could help your business.

Permanent magnets
