Home Industrial Technologies Ultra thin high-performance permanent magnets

Ultra thin high-performance permanent magnets.


Ultra thin high-performance permanent magnets based on Nd-Fe-B and Sm-Co alloys.


Ultra thin high-performance Nd-Fe-B and Sm-Co permanent magnets of the thickness in the range of 50-1000 microns are produced by the cold deformation of melt-spun alloys. The fabrication process of miniature nanocomposite magnets includes the dragging and rolling of quenched alloy. The technology allows to produce many standard magnets with high magnetic characteristics, but our strength lies in the ability to modify our products to the specific requirements of miniature assembly manufactures or produce virtually any permanent magnet systems with optimum design and performance.


  • Remanance  Br=1,0-1.3 T
  • Coercivity Нс=800-1200 кА/m
  • Maximum energy product (ВН) max =250-300 кJ/m3
  • Work temperature Т= -100 to 2000С

Main Advantages

  • High magnetic properties per specific volume of magnetic material
