Neodymium is a rare earth metal element with the chemical symbol Nd. Neodymium is very rare in nature and is usually found in ores in the form of neodymium oxide.

Neodymium is a very important material because it is one of the main raw materials for the manufacture of high-performance permanent magnets. Permanent magnets are a powerful magnetic material, which is widely used in many fields, such as electric vehicles, computer hard drives, smart phones, audio equipment and medical equipment.

Neodymium permanent magnets are composed of elements such as neodymium, iron and boron, and are one of the strongest permanent magnets available. It has the advantages of high permeability, high corrosion resistance and high energy density. The demand for neodymium permanent magnets is increasing due to the growing global demand for energy-saving and environmentally friendly technologies that can improve the efficiency of electric vehicles and other electronic devices.
