Essential for wide-ranging industrial applications#

Magnetic materials are essential for wide-ranging industrial applications. Due to current ambitions to develop an energy as well as resource efficient society the requirements for magnetic materials concerning magnetic properties and especially energy density are increasing. For high-tech applications (smartphones, computers, etc.), applications for renewable energies (wind power generators) and electric vehicles (electric motors) high-performance magnetic materials like Nd-Fe-B are necessary. Due to their high energy product they are for the time being not substitutable by alternative magnetic materials. Rare earth elements used for the production of Nd-Fe-B magnets are therefore of great strategic importance.

 

To secure a sustainable supply of our industries with high performance permanent magnets and the raw materials used for their production we address the following subjects:

  • Recycling technologies for End of Life-magnets and post-industrial scrap
  • Substitution of critical elements (in particular rare earths)
  • Resource strategies for magnetic materials
