The main uses of neodymium metal include the following aspects:
Neodymium iron boron permanent magnet material: Neodymium iron boron permanent magnet material is one of the main applications of neodymium metal, known as the "king of permanent magnets" due to its high magnetic energy product. It is widely used in high-tech products such as electronics, machinery, computer hard drives, MRI machines, etc.
Nonferrous metal materials: Adding 1.5-2.5% neodymium metal to magnesium or aluminum alloys can significantly improve their high-temperature performance, airtightness, and corrosion resistance, making them suitable for aerospace materials.
Laser technology: Neodymium doped yttrium aluminum garnet (YAG) lasers can generate short wave laser beams, which are used for welding and cutting thin materials in industry, as well as surgical knife substitutes in medicine.
Other applications: Neodymium metal is also used in the manufacture of optical glass, permanent magnet alloys, flint, and glazes. In addition, neodymium atomic absorption standard substances are also used in atomic absorption spectroscopy analysis for calibrating instruments, evaluating analytical methods, and conducting quality control.
