· Co4 Ho2

Co4Ho2 is an intermetallic compound combining cobalt and holmium, belonging to the rare-earth transition metal alloy family. This material is primarily of research interest for magnetic and electronic applications, as the combination of cobalt's ferromagnetic properties with holmium's strong magnetic moments creates potential for high-performance magnetic devices and advanced materials. While not yet widely commercialized, Co4Ho2 and similar rare-earth cobalt intermetallics are being investigated for next-generation permanent magnets, magnetocaloric cooling systems, and specialized electronic components where enhanced magnetic coupling is valuable.

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.
