Neodymium (NdFeB) magnets are rare-earth permanent magnets known for their exceptional magnetic strength and compact size. Compared to ferrite and Alnico, NdFeB magnets provide 5–15 × higher energy density, making them ideal for miniaturized designs. Since their invention in 1983, sintered neodymium magnets have become the cornerstone of modern magnetic applications.
At Shanghai Taixiong Magnetic Industry Co., Ltd, we specialize in OEM & custom magnet production, offering full support from material selection to final coating, packaging, and global delivery.
Sintered Neodymium Iron Boron Magnets Introduced in 1983, the Sintered Neodymium Iron Boron (NdFeB) magnet stands as a remarkable innovation primarily composed of neodymium, iron, and boron. Its intrinsic coercivity far surpasses that of ferrite by a remarkable margin of 5-10 times, and exceeds aluminum-nickel-cobalt by a remarkable margin of 6-10 times. Remarkably, it boasts a maximum energy product that is a staggering 5-15 times greater than ferrite, firmly establishing it as the pinnacle of contemporary magnetic materials. In comparison with conventional magnetic materials, it not only exhibits exceptional magnetic properties but also stands out for its remarkable cost-effectiveness, thereby unlocking an extensive array of possibilities for magnetic material applications. |  |
