Heavy Rare Earth Element Free Neodymium Sintered Magnet (HRE-Free)

The most powerful magnet. It enables miniaturization and high performance of products.

Neodymium magnets (NdFeB magnets) are the permanent magnet materials with the highest maximum energy product. They are composed of neodymium (Nd), iron (Fe), boron (B), and light rare earth elements, providing high magnetic energy product, coercivity, and stability at room temperature. They come in various shapes, are easy to process, and are essential for high-efficiency motors and precision electronic devices. The sintering method involves high-temperature melting, rapid cooling, and heat treatment of powders to form a high-density fine structure. It excels in demagnetization resistance and temperature stability with high intrinsic coercivity and maximum energy product, allowing for prototype production without molds. It is ideal for small quantities of diverse and lightweight products. Shinki Industries offers a lineup of heavy rare earth-free neodymium sintered magnets. By not using dysprosium (Dy), terbium (Tb), or gadolinium (Gd), and through grain refinement, grain boundary diffusion, and special heat treatment, we ensure high coercivity and heat resistance. This avoids fluctuations in rare earth prices and supply risks, achieving stable supply. With a temperature range from 0°C to 150°C, it is an ideal solution for lightweight, high-efficiency, and low-cost applications in consumer electronics, permanent magnet motors, and green energy fields.
