metal

· JVASP-21597· HoNi4B

HoNi4B is an intermetallic compound combining holmium, nickel, and boron, belonging to the rare-earth transition metal boride family. This material is primarily of research and development interest, studied for its potential in high-temperature applications and magnetic device components where rare-earth metallics offer enhanced performance. The addition of boron to nickel-rare-earth systems typically enhances hardness, thermal stability, and magnetic properties compared to binary nickel-rare-earth alloys.
