HoCo4Ni
metal· JVASP-99981· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
