Sintered Neodymium Magnet
Introduction
Sintered neodymium magnets, also known as sintered NdFeB magnets, are the best choice for high-end commercial motors due to their high energy and shape variety.
In spite of its outstanding performance, the sintered neodymium magnet is vulnerable to corrosion and high temperature. For prevention of corrosion, it needs a protective coating which is commonly a three-layer coating composed of Ni-Cu-Ni.
To deal with the issue of heat, heavy rare earth elements are added to promote the temperature tolerance of sintered neodymium magnets.
To address price fluctuations and supply risks of heavy rare earths, New Favor Industry offers Heavy Rare Earth Free Neodymium-Iron-Boron (NdFeB) magnets. By applying grain boundary diffusion technology and innovative alloy design, these magnets achieve high magnetic performance and thermal resistance without the need for Dy or Tb, making them suitable for electric vehicles, renewable energy, and other applications.Heavy Rare Earth Free NdFeB effectively reduces material costs and supply chain risks, avoids export control restrictions, and aligns with sustainability trends, providing manufacturers with a stable and rapid supply solution.
New Favor Industry has established a complete range of Heavy Rare Earth Free magnet grades to meet diverse industrial demands.
