Holmium Metal Ho CAS 7440-60-0 For Additive Of NdFeB Magnets

Holmium is a rare metallic element with the chemical symbol Ho and atomic number 67. It belongs to the lanthanide series and has a silver-white appearance, soft texture and good ductility. Holmium is also increasingly widely used in aerospace, electronics, medical equipment and other fields. For example, in aerospace, holmium iron alloys are used to make high-performance magnetic materials; In the medical field, holmium laser is widely used in stone dismemberment and other operations. Although the amount of holmium is not very large at present, it has great potential and is expected to play an important role in more fields in the future.
