NdFeB Magnets
What are NdFeB magnets？NdFeb (neodymium-iron-boron) magnets are currently the strongest permanent magnetic material, composed of neodymium, iron, and boron. With exceptionally high magnetic energy product and coercivity, they are known as the “King of Magnets” and are widely used in motors, wind power generation, electronic devices, and medical equipment. They are manufactured through two main processes: sintered magnets, which offer superior magnetic performance but require anti-corrosion coatings, and bonded magnets, which are easier to process but have slightly weaker magnetic properties. However, NdFeB magnets also face challenges such as oxidation susceptibility, demagnetization at high temperatures, and heavy reliance on rare earth resources. Current research focuses on improving their thermal stability, reducing rare earth usage, and developing recycling technologies to address cost and environmental concerns.
NdFeB Composition
Sintered neodymium iron boron (commonly referred to as sintered NdFeB, with the chemical formula Nd₂Fe₁₄B) is a high-performance permanent magnet material manufactured through powder metallurgy processes. Its primary components are neodymium (Nd), iron (Fe), and boron (B), often supplemented with rare earth elements such as dysprosium (Dy) and terbium (Tb) to enhance coercivity and temperature stability. The microstructure consists mainly of a tetragonal Nd₂Fe₁₄B crystal phase, with grain boundaries enriched with rare earth elements to optimize magnetic properties.
