· Ho12 Co4

Ho12Co4 is an intermetallic compound combining holmium (a rare-earth element) with cobalt, likely investigated for magnetic, thermal, or structural applications given the strong ferromagnetic properties associated with holmium-cobalt systems. This is a research-phase material rather than a production commodity; it belongs to the family of rare-earth transition-metal compounds that have shown potential in permanent magnets, magnetostrictive devices, and high-temperature applications. Engineers would consider this material primarily in specialized research contexts where the unique magnetic behavior or thermal stability of holmium-cobalt phases offers advantages over conventional alternatives, though limited commercial availability and processing complexity currently restrict its use to laboratory and prototype stages.

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.
