Neodymium Magnet

Neodymium magnet is a highly efficient and powerful permanent magnet, composed of neodymium (Nd), iron (Fe) and boron (B), commonly known as NdFeB magnet. It has an extremely high magnetic energy product (BHmax) and produces a strong magnetic field in a small volume. Although the performance may decrease at high temperatures, certain specific formulas can maintain magnetism. Compared with other permanent magnetic materials, NdFeB magnets have advantages in size and weight and are suitable for high-density applications. They are the strongest commercial permanent magnets known to date, and are widely used in various high-performance technologies and equipment, becoming an indispensable and important material in modern technology. HuanTongcx as a professional neodymium magnet manufacturer which offers neodymium magnet products and custom neodymium magnet.
