HoCo4Ni

HoCo4Ni is a rare-earth cobalt-nickel intermetallic compound containing holmium, cobalt, and nickel. This material belongs to the family of high-performance magnetic and structural alloys that combine rare-earth elements with transition metals to achieve exceptional hardness, thermal stability, and magnetic properties. While not widely commercialized as a standard engineering material, HoCo4Ni represents research interest in advanced applications requiring materials that operate under extreme conditions—particularly where conventional superalloys or permanent magnets reach their performance limits.
